  - Exact error: ERROR: failed to calculate checksum of ref dm0crafjnw8l43ifl6uhde0ck::xvjhsrzs1xuomeumy2tyv7rr7: "/app/dist": not found
  - Exit code: not shown in log

- Failing command/step
  - [stage-1 3/5] COPY --from=build /app/dist ./dist

- Missing packages or files mentioned
  - Missing file: /app/dist (the built artifacts directory expected from the build stage)

- Version mismatch information
  - Base image uses Node 18 (FROM node:18-slim), but many dependencies report engine requirements of Node >= 20 (e.g., @nestjs/core@11.1.10 requires node >= 20; @apollo/server@5.4.0 requires node >= 20).
  - Numerous EBADENGINE warnings indicating unsupported engine versions for current Node v18.20.8 and npm 10.8.2.
  - This suggests a potential compatibility issue between the project dependencies and the Node version in the base image.

  - Exit code: 127
  - Additionally shown: ERROR: failed to build: failed to solve: process "/bin/sh -c npm ci --omit=dev --silent" did not complete successfully: exit code: 127

- Failing command/step:
  - [stage-1 4/5] RUN npm ci --omit=dev --silent

- Missing packages or files mentioned:
  - husky not found (likely Husky binary or script not present in the image when running npm ci)

- Version mismatch info:
  - No explicit version mismatch reported. Base image used: node:20-slim. A casing warning appears previously, but no version mismatch is shown in the failure.

- Context notes
  - The build stage ran npm ci and npm run build, but the produced dist directory is not present for COPY from the build stage to succeed.

- Missing packages or files mentioned
  - None reported. The failure is due to a syntax/quoting issue in the RUN command, not a missing package or file. The dist/ directory already existed (mkdir -p dist was run earlier).

- Version mismatch / related notes
  - Base image: docker.io/library/node:20-slim (digest sha256:17281e8d1dc4d671976c6b89a12f47a44c2f390b63a989e2e327631041f544fd)
  - Dockerfile warnings (non-fatal): FromAsCasing: 'as' and 'FROM' keywords' casing do not match (line 1) and (line 16) (two warnings)
  - No explicit version mismatch error; the issue is quoting/escaping in the final RUN command.

- Failing command/step

- Missing packages or files mentioned
  - The step intends to create a fallback file: dist/main.js
  - Missing/target file: dist/main.js
  - The error occurred while attempting to generate dist/main.js via a here-doc in the RUN command

  - Note: A warning about casing: FromAsCasing: 'as' and 'FROM' keywords' casing do not match (line 1)
  - No explicit version mismatch reported beyond the above; Debian bookworm packages were installed during the build step.

- Failing command/step:
  - [runtime 5/5] COPY --from=builder /app/dist ./dist

- Exact error message and exit code:
  - ERROR: failed to calculate checksum of ref dm0crafjnw8l43ifl6uhde0ck::symajt5r3ywgt4t1z8ataj8i3: "/app/dist": not found
  - Exit code: not explicitly shown in the log

- Missing packages or files mentioned:
  - /app/dist not found (the dist directory expected from the builder stage)

- Version mismatch info:
  - None reported

- Context / notes:
  - The error occurs during the final runtime stage while attempting to copy artifacts from the builder: COPY --from=builder /app/dist ./dist
  - The builder's dist output was not present at /app/dist, causing the checksum calculation to fail. This suggests the build step (npm run build) did not produce /app/dist in the builder, or the path differs from what the Dockerfile expects. Check that the build actually emits dist to /app/dist (or adjust the COPY path accordingly).
