Failing step
- [9/9] RUN pip install --no-cache-dir -e .

Exact error message and exit code
- pdm.backend.exceptions.ConfigError: Cannot find the version from SCM or SCM isn't detected.
  You can still specify the version via environment variable `PDM_BUILD_SCM_VERSION`, or specify `fallback_version` config.
- metadata-generation-failed
- Encountered error while generating package metadata.
- error: metadata-generation-failed
- The build ultimately fails with: 
  ERROR: failed to build: failed to solve: process "/bin/sh -c pip install --no-cache-dir -e ." did not complete successfully: exit code: 1

Missing packages or files mentioned
- None explicitly cited. The error is due to SCM-based version detection failing during editable install, not a missing system package or file.

Version mismatch / guidance notes
- The issue is a packaging/version-detection problem in the editable install step using PDM.
- Suggested remediation in the error output:
  - Set environment variable PDM_BUILD_SCM_VERSION, or
  - Configure a fallback_version in PDM.

Summary of Docker build error

- Failing step (command/step):
  - [ 9/10] RUN pdm update --no-editable --prod --frozen-lockfile

- Exact error message and exit code:
  - [BuildError]: Build backend raised error: Showing the last 10 lines of the build output:
    ...
    pdm.backend.exceptions.ValidationError: project.readme.file: Readme file not found ('README.md')
  - WARNING: Add '-v' to see the detailed traceback
  - ERROR: process "/bin/sh -c pdm update --no-editable --prod --frozen-lockfile" did not complete successfully: exit code: 1

- Failing/missing file:
  - README.md is missing (Readme file not found)

- Version/compatibility information observed
  - Base image uses Python 3.11: FROM docker.io/library/python:3.11-slim (Debian trixie)
  - PDm/pip-related warnings during resolution indicate Python version compatibility adjustments, e.g.:
    - Skipping click/* versions that require Python>=3.10 due to lock targets (Python>=3.8)
  - Build environment shows DEPRECATED: cross_platform strategy is deprecated in favor of lock targets
  - Several package resolution messages noting Python 3.11 compatibility versus lock targets (>=3.8)

Notes
- All prior steps before this RUN pdm update completed, but the build fails due to the missing README.md referenced by the PDm lock/update process. Addressing the repository to include README.md or adjusting the PDm configuration to not require it should allow the build to proceed.

- Failing step (command): RUN pdm update --no-editable --prod --frozen-lockfile (Dockerfile step 9/10)

- Exact error message and exit code:
  - exit code: 1
  - pdm.backend.exceptions.ConfigError: Cannot find the version from SCM or SCM isn't detected. 
  - You can still specify the version via environment variable `PDM_BUILD_SCM_VERSION`, or specify `fallback_version` config.
  - WARNING: Add '-v' to see the detailed traceback

- Summary of failure:
  - The PDm build cannot determine the project version from SCM. As a result, pdm update fails with a ConfigError and the build stops with exit code 1.

- Missing files/packages referenced:
  - Root cause implies SCM version not detected; to fix, provide a SCM version via environment variable PDM_BUILD_SCM_VERSION or configure a fallback_version in PDm.

- Version mismatch / notes:
  - Base image uses Python 3.11-slim, while the lockfile targets Python >= 3.8; there are warnings about package versions (e.g., click) requiring Python >= 3.10, leading PDm to skip certain candidates. These are warnings and not the direct cause, but indicate a Python-version mismatch between the environment and some package constraints.
