Summary of Docker build error

- Exact error message and exit code
  - error Command "build" not found.
  - Exit code: 1
  - Additional lines:
    - Command failed.
    - Command: /usr/local/bin/node
    - Arguments: /opt/yarn-v1.22.22/lib/cli.js build
    - Directory: /app/packages/graphpack

- Failing command/step
  - [build 6/6] RUN yarn workspace graphpack build

- Missing packages or files mentioned
  - Graphpack workspace has no build script defined; Yarn attempted to run a script named "build" but it does not exist in that workspace’s package.json (Directory: /app/packages/graphpack).

- Version mismatch info
  - No explicit version mismatch reported.
  - Used yarn v1.22.22 and Node base images shown (node:18-bullseye / node:18-bullseye-slim). No mismatch notes.

Notes
- Likely fix: define a build script for the graphpack workspace (in its package.json) or adjust the Dockerfile to run an existing script.

Summary (under 1500 chars):

- Failing command/step:
  - RUN npm install --workspaces

- Exact error message and exit code:
  - npm error No workspaces found!
  - npm error A complete log of this run can be found in: /root/.npm/_logs/2026-03-22T14_18_25_658Z-debug-0.log
  - Exit code: 1
  - The failure occurred in Dockerfile:9 during the build step [build 5/7].

- Missing packages or files mentioned:
  - No workspaces found! (likely because the root package.json does not define any workspaces or there are no workspace packages configured)
  - Note: package.json and yarn.lock were copied prior to this step, but no workspaces are defined.

- Version mismatch info:
  - None reported. The log shows base images (node:18-bullseye and node:18-bullseye-slim) used, but no version mismatch errors.

Failing step
- build 7/7: RUN npx webpack --config packages/graphpack/config/webpack.config.js

Exact error message and exit code
- ERROR: failed to build: failed to solve: process "/bin/sh -c npx webpack --config packages/graphpack/config/webpack.config.js" did not complete successfully: exit code: 1

Missing packages / files mentioned
- The following package would be installed: webpack@5.105.4 (not found)
- webpack-cli is not installed; CLI must be installed
- Prompt observed: "Do you want to install 'webpack-cli' (yes/no):"
- The log also notes: "We will use 'yarn' to install the CLI via 'yarn add -D webpack-cli'."

Version / dependency notes
- webpack@5.105.4 is the version the installer plans to use
- npm notifies a new major version is available: 10.8.2 -> 11.12.0 (not directly related to the failure, but shown in the log)

Context
- Dockerfile reference: Dockerfile:17
- The error stems from an interactive prompt in a non-interactive Docker build environment, causing the npx webpack command to fail with exit code 1.

Summary (under 1500 chars):

- Exact error message and exit code:
  - ERROR: process "/bin/sh -c yarn workspaces focus graphpack --production" did not complete successfully: exit code: 1
  - The command output:
    - yarn workspaces v1.22.19
    - error Invalid subcommand. Try "info, run"
    - info Visit https://yarnpkg.com/en/docs/cli/workspaces for documentation about this command.

- Failing command/step:
  - [build 7/9] RUN yarn workspaces focus graphpack --production

- Missing packages or files mentioned:
  - None explicitly mentioned.

- Version mismatch info:
  - Yarn version shown: v1.22.19 (via corepack/yarn setup)
  - The error indicates "workspaces focus" is not a valid subcommand for Yarn v1.22.19; this feature (focus subcommand for workspaces) exists in newer Yarn versions (Yarn 2+). The session indicates a potential version mismatch between the command used and the installed Yarn version.

Summary of Docker build error

- Failing step
  - [build 8/8] RUN yarn build-graphpack (Dockerfile: line 20)

- Exact error message and exit code
  - Error: Cannot find module 'webpack'
  - Require stack:
  - /app/scripts/build-graphpack.js
  - Node.js v18.20.8
  - exit code: 1
  - error Command failed with exit code 1.

- Missing packages or files mentioned
  - Module not found: webpack (the build-graphpack.js script requires webpack but it isn’t installed in the runtime environment)

- Version mismatch / environment details
  - Base images involved: node:18-slim and node:18-bullseye
  - Node.js version reported: v18.20.8
  - Yarn version: 1.22.19 (invoked via Corepack; “The local project doesn't define a 'packageManager' field. Corepack will now add one referencing yarn@1.22.19+sha512...”)
  - Build context shows Corepack enabling yarn 1.22.19 and running yarn build-graphpack

Possible quick fix (not in log)
- Ensure webpack is declared in dependencies or devDependencies and installed (e.g., yarn add webpack) so that yarn install includes it before running build-graphpack.

}

Failing step
- [build 8/8] RUN yarn build-graphpack

Exact error message and exit code
- Error: "Failed to load webpack config: Error: Cannot find module 'friendly-errors-webpack-plugin'"
- Exit code: 1
- NODE_MODULE error: code: 'MODULE_NOT_FOUND'
- Command failed with exit code 1

Missing packages or files mentioned
- Missing module: friendly-errors-webpack-plugin (Cannot find module 'friendly-errors-webpack-plugin')
- Require stack:
  - /app/packages/graphpack/config/webpack.config.js
  - /app/scripts/build-graphpack.js

Version/manager information (preserved)
- Corepack note during install: The local project doesn't define a 'packageManager' field. Corepack will now add one referencing yarn@1.22.19+sha512.ff4579ab459bb25aa7c0ff75b62acebe576f6084b36aa842971cf250a5d8c6cd3bc9420b22ce63c7f93a0857bc6ef29291db39c3e7a23aab5adfd5a4dd6c5d71.
- Yarn version used: v1.22.19 ( yarn install v1.22.19; corepack prepare yarn@1.22.19 --activate)
- Base images involved: node:18-slim and node:18-bullseye (build uses Node 18)
- This version/manager info appears as part of Corepack/Yarn setup, not an explicit version mismatch error.

Note: This is followed by:
Dockerfile:15
ERROR: failed to build: failed to solve: process "/bin/sh -c yarn build-graphpack" did not complete successfully: exit code: 1

- Version/mismatch/context info:
- Node.js version: v18.20.8
- Yarn: v1.22.22
- Corepack warning: The local project doesn't define a 'packageManager' field. Corepack will now add one referencing yarn@1.22.22+sha512...
- Base images referenced: node:18-slim and node:18-bullseye

- Missing packages/files mentioned:
- The webpack module is not found (missing from dependencies/lockfile), required by /app/scripts/build-graphpack.js

- Additional context:
- The failure occurs during the graphpack build script, which expects webpack to be installed. To fix, ensure webpack is listed in dependencies/devDependencies and installed (e.g., yarn add webpack, then yarn install with an up-to-date lockfile).

- Failing command/step:
  - [builder 3/7] RUN npm install -g yarn@1.22.19
  - (Same command appears again at Dockerfile:20)

- Exact error message and exit code:
  - npm error EEXIST: file already exists
  - path /usr/local/bin/yarn
  - File exists: /usr/local/bin/yarn
  - Remove the existing file and try again, or run npm with --force to overwrite files recklessly.
  - A complete log of this run can be found in: /root/.npm/_logs/2026-03-22T14_38_56_827Z-debug-0.log
  - ERROR: process "/bin/sh -c npm install -g yarn@1.22.19" did not complete successfully: exit code: 1

- Missing packages or files mentioned:
  - No missing packages; the issue is a pre-existing file conflict. Specifically, /usr/local/bin/yarn already exists.

- Version mismatch / related notes:
  - New major version of npm available! 10.8.2 -> 11.12.0 (To update: npm install -g npm@11.12.0)
  - Dockerfile indicates use of Yarn 1.x for workspace compatibility (as part of the command being run)

- Context:
  - The build failed during global installation of yarn@1.22.19 due to an existing /usr/local/bin/yarn binary.

- Failing step (exact command): RUN yarn workspace graphpack build (builder 7/7)
- Exact error message and exit code:
  - error Command "build" not found.
  - Exit code: 1
- Context of failure:
  - Directory: /app/packages/graphpack
  - Command failed.
- What’s missing or misconfigured:
  - The graphpack workspace does not define a build script in its package.json, so the Yarn workspace build command has nothing to run.
- Version/environment notes:
  - Yarn v1.22.19 (as shown by “yarn install v1.22.19” and “yarn workspace v1.22.19”)
  - Corepack warning: The local project doesn't define a 'packageManager' field. Corepack will now add one referencing yarn@1.22.19+sha512.ff4579ab459bb25aa7c0ff75b62acebe576f6084b36aa842971cf250a5d8c6cd3bc9420b22ce63c7f93a0857bc6ef29291db39c3e7a23aab5adfd5a4dd6c5d71.
- Quick fix suggestion:
  - Define a build script in /app/packages/graphpack/package.json (e.g., "scripts": { "build": "your-build-command" }) or modify the Dockerfile to run an existing script.

Summary (concise, actionable)

- Failing step (failing command): [builder 7/7] RUN node scripts/build-graphpack.js (Dockerfile: line 16)
- Exit code: 1
- Exact error message and stack excerpt:
  Node.js v18.20.8
  Error: Cannot find module 'webpack'
  Require stack:
    '/app/scripts/build-graphpack.js'
  at ... (full trace shown in log)
  code: 'MODULE_NOT_FOUND'
- Missing packages or files mentioned:

  (Then:) error Command failed with exit code 1.
- Missing packages/files mentioned: The process cannot find the required dependency webpack ("Cannot find module 'webpack'"), indicating webpack is not installed or not resolvable in this environment.
- Version information:
  - Node.js version: v18.20.8
  - Yarn version: 1.22.19 (as prepared by Corepack during the run)
  - Base image: node:18-slim
  - Corepack warning noted earlier about adding a packageManager field (noting the environment behavior)
- Context: This occurs during graphpack build script execution (build-graphpack.js), before successful graphpack creation.
