Failing step:
- [builder 6/6] RUN npm run build (Dockerfile:12)

Exact errors and exit code:
- Top-level: ERROR: failed to build: failed to solve: process "/bin/sh -c npm run build" did not complete successfully: exit code: 1
- Runtime error during build:
  - Error: Failed to launch the browser process: Code: 127
  - stderr: /root/.cache/puppeteer/chrome/linux-145.0.7632.77/chrome-linux64/chrome: error while loading shared libraries: libnspr4.so: cannot open shared object file: No such file or directory
  - TROUBLESHOOTING: https://pptr.dev/troubleshooting
  - Node.js v20.20.1

Missing packages/files mentioned:
- libnspr4.so (indicates the libnspr4 library is not installed in the image)

Version information / mismatches:
- Base image / Node: node:20-bullseye-slim (Node.js v20.20.1 reported in log)
- Puppeteer Chromium version referenced: linux-145.0.7632.77 (path shown in error)
- NPM version notice: New major version available (10.8.2 -> 11.11.1) (noting a version update, not an error)

Notes:
- The build fails during the Puppeteer browser launch step invoked by npm run build due to a missing libnspr4 shared library.

  - /root/.cache/puppeteer/chrome/linux-145.0.7632.77/chrome-linux64/chrome: error while loading shared libraries: libatk-1.0.so.0: cannot open shared object file: No such file or directory
  - TROUBLESHOOTING: https://pptr.dev/troubleshooting
  - Node.js v20.20.1
  - Dockerfile:18
  - ERROR: failed to build: failed to solve: process "/bin/sh -c npm run build" did not complete successfully: exit code: 1

- Missing packages or files mentioned:
  - libatk-1.0.so.0 (not found). This corresponds to the libatk1.0-0 package; it is not installed in the image, causing Chromium (Puppeteer) to fail to launch.

- Version mismatch/info:
  - Base image uses Node 20 (bullseye family): node:20-bullseye and node:20-bullseye-slim
  - Puppeteer Chromium binary referenced: chrome-linux64/chrome (linux-145.0.7632.77)
  - Node.js version shown in the error: v20.20.1

Root cause: Puppeteer cannot launch Chromium due to a missing system library (libatk-1.0.so.0). Add libatk1.0-0 (and potentially related GUI libs) to the image before running npm run build.

  - Error prior to exit: “Error: Failed to launch the browser process:  Code: 127”
  - Stderr snippet: “/root/.cache/puppeteer/chrome/linux-145.0.7632.77/chrome-linux64/chrome: error while loading shared libraries: libatk-bridge-2.0.so.0: cannot open shared object file: No such file or directory”
  - Node.js version shown: Node.js v20.20.1
  - Troubleshooting hint included: TROUBLESHOOTING: https://pptr.dev/troubleshooting

- Version/size context:
  - Chrome binary used by Puppeteer: linux-145.0.7632.77
  - Runtime base image uses Node 20 (node:20-bullseye-slim)

- Missing packages/files mentioned:
  - libatk-bridge-2.0.so.0 is missing (likely provided by libatk-bridge2.0-0). The error indicates this shared library is not present in the container at runtime.

- Summary of cause:
  - Puppeteer-initiated Chrome cannot start due to a missing system library (libatk-bridge-2.0.so.0), causing the npm run build step to fail with exit code 1.

- Actionable note:
  - Ensure the runtime image has libatk-bridge2.0-0 (providing libatk-bridge-2.0.so.0) installed prior to npm run build.

Failing step and exit
- Failing command/step: Builder step 7/7, RUN npm run build (Dockerfile line 19)
- Exit code: 1
- Error summary from logs:
  - Error: Failed to launch the browser process:  Code: 127
  - stderr:
    /root/.cache/puppeteer/chrome/linux-145.0.7632.77/chrome-linux64/chrome: error while loading shared libraries: libcups.so.2: cannot open shared object file: No such file or directory
  - TROUBLESHOOTING: https://pptr.dev/troubleshooting
  - Node.js v20.20.1

Missing packages/files mentioned
- libcups.so.2 missing (runtime dependency); implies libcups2 not installed.
- Likely fix: install libcups2 (e.g., apt-get install -y libcups2)

Version/compatibility notes
- Base image: node:20-bullseye-slim; Node.js version in log: v20.20.1
- Puppeteer Chrome binary referenced: linux-145.0.7632.77
- Build context shows Debian bullseye system packages being installed, but libcups2 is not present, causing Chrome to fail to launch during the build step.

Failing step

Exact error message and exit code
- Error: Failed to launch the browser process:  Code: 127
- stderr:
  /root/.cache/puppeteer/chrome/linux-145.0.7632.77/chrome-linux64/chrome: error while loading shared libraries: libxkbcommon.so.0: cannot open shared object file: No such file or directory
- Node.js v20.20.1
- The overall step exit code: 1
- Docker build note: ERROR: failed to build: failed to solve: process "/bin/sh -c npm run build" did not complete successfully: exit code: 1

Missing packages or files mentioned
- Missing shared library: libxkbcommon.so.0 (libxkbcommon0 not installed), required by Chromium/Puppeteer
- The apt-get install step did not include libxkbcommon0

Version mismatch info
- Base image context shows Node.js v20 (node:20-bullseye and node:20-bullseye-slim)
- Puppeteer is trying to run Chrome/Chromium (chrome-linux64) in /root/.cache/puppeteer with Chrome version linux-145.0.7632.77
- The error indicates a missing system library (libxkbcommon.so.0) rather than a Node version mismatch, but the Node/Chrome tooling versions are as shown above (Node v20.20.1 in the error context).

Summary of Docker build error

- Failing command/step
  - RUN npm run build (builder 7/7)

- Exact error message and exit code
  - Exit code: 1 (build step did not complete successfully)
  - Error message from the build:
    - "Error: Failed to launch the browser process:  Code: 127"
    - Stderr excerpt:
      "/root/.cache/puppeteer/chrome/linux-145.0.7632.77/chrome-linux64/chrome: error while loading shared libraries: libXcomposite.so.1: cannot open shared object file: No such file or directory"
    - "TROUBLESHOOTING: https://pptr.dev/troubleshooting"
  - Runtime detail shown:
    - Node.js v20.20.1

- Missing packages or files mentioned
  - The error indicates a missing shared library: libXcomposite.so.1
  - This implies the package libxcomposite1 (providing libXcomposite.so.1) is not installed
  - The apt-get install command in the build installs several lib* packages but does not include libxcomposite1

- Version/mismatch information
  - Base images involved:
    - Node image: 20-bullseye-slim (runtime) and 20-bullseye (builder)
  - Node.js version reported in the error: Node.js v20.20.1
  - Puppeteer attempting to launch Chrome from a cached install: /root/.cache/puppeteer/chrome/linux-145.0.7632.77/chrome-linux64/chrome

Notes
- The root cause is the missing libXcomposite.so.1 (libxcomposite1 package). Adding libxcomposite1 to the apt-get install line should allow Puppeteer to launch Chrome during the build.

- Failing command/step
  - [builder 7/7] RUN npm run build
  - Dockerfile line: 19

- Missing packages or files mentioned
  - Missing shared library: libXdamage.so.1 (provided by libxdamage1)
  - Evidence: chromium/puppeteer cannot load libXdamage.so.1
  - The runtime apt-get install step did not include libxdamage1 (libXdamage1) in the installed packages

- Version mismatch information
  - Node.js version: v20.20.1
  - Puppeteer/Chromium Chrome version shown: chrome-linux64/chrome: 145.0.7632.77
  - Root cause is a missing system library (libxdamage1) rather than a strict version mismatch; install libxdamage1 to resolve.

Summary (under 1500 chars):

- Exact error message and exit code:
  - Error: Failed to launch the browser process:  Code: 127
  - /root/.cache/puppeteer/chrome/linux-145.0.7632.77/chrome-linux64/chrome: error while loading shared libraries: libXfixes.so.3: cannot open shared object file: No such file or directory

- Failing command/step:
  - [builder 7/7] RUN npm run build

- Missing packages or files mentioned:
  - libXfixes.so.3 is missing (likely provided by libxfixes3). Install libxfixes3 to resolve.

- Version mismatch info:
  - Node.js v20.20.1 (no explicit version mismatch indicated; failure due to missing system library)
  - Also a npm notice about a newer major version available (10.8.2 -> 11.11.1) but not the cause of the failure

Notes:
- The failure occurs during the build when Puppeteer tries to launch Chromium as part of npm run build. The root cause is a missing library (libXfixes.so.3) not provided by the installed Debian libs in the image. Adding libxfixes3 to the apt-get install step should resolve.

Summary of the Docker build error

- Exact error message and exit code
  - Error: Failed to launch the browser process:  Code: 127
  - chrome: error while loading shared libraries: libgbm.so.1: cannot open shared object file: No such file or directory
  - Node.js v24.14.0
  - The overall build step reports: process "/bin/sh -c npm run build" did not complete successfully: exit code: 1

- Failing command/step
  - Dockerfile: RUN npm run build (builder stage 7/7)

- Missing packages or files mentioned
  - libgbm.so.1 is missing (likely need package libgbm1 to be installed)

- Version mismatch/info
  - Base images used: node:lts-slim and node:lts
  - Puppeteer/Chrome usage during build: chrome-linux64 with path /root/.cache/puppeteer/chrome/linux-145.0.7592... (shows Chrome V145 context)
  - Node.js version shown: v24.14.0

- Practical fix (brief)
  - Install libgbm1 in the builder image, e.g. add to apt-get install line:
    libgbm1
  - Or switch to a base image that includes libgbm1 by default.

Summary (concise, actionable)

- Exact error message and exit code
  - ERROR: process "/bin/sh -c bash -lc 'cat > /app/run.js <<"JS"\ntry { require("./pkg/sinon.js"); console.log("sinon loaded"); } catch (e) { console.error("load failed", e); process.exit(1); }\nJS'" did not complete successfully: exit code: 2
  - Additional shell output:
    - bash: line 1: warning: here-document at line 1 delimited by end-of-file (wanted `JSntry')
    - bash: -c: line 1: syntax error near unexpected token `('

- Failing command/step
  - Runtime stage 4/4: RUN bash -lc 'cat > /app/run.js <<"JS" … JS'

- Missing packages or files mentioned
  - No explicit missing packages or files are reported in this error excerpt. The failure is due to a syntax error in the here-document used in the RUN command, not a missing file.

- Version mismatch info
  - Node engine mismatch warnings during npm ci (example excerpt):
    - EBADENGINE Unsupported engine {
        package: '@es-joy/jsdoccomment@0.84.0',
        required: { node: '^20.19.0 || ^22.13.0 || >=24' },
        current: { node: 'v18.20.8', npm: '10.8.2' }
      }
  - Many packages require Node 20+; current Node version is v18.20.8.
  - npm notice: New major version of npm available! 10.8.2 -> 11.11.1

Notes
- The build proceeds up to the RUN that generates /app/run.js; the failure is a syntax/error in the here-document, not a runtime import error of the built package. Fixing the HERE-DOC quoting/termination in the Dockerfile (or using a simpler echo/printf approach) should resolve the exit code 2. If you intend to run the build with Node 18, you may also need to align engine requirements or switch to a Node 20+ base image to satisfy the EBADENGINE warnings seen in npm ci.
