How to detect:
When running 'bentoml containerize', the build process fails with NotImplementedError during Docker image construction. The error occurs in the construct_build_args method when processing command arguments. This is caused by incompatibility with Click CLI library version 8.3.0, which is installed by default when pyproject.toml doesn't pin the Click version.
Recommended action:
Downgrade Click to version 8.2.1 using 'pip install click==8.2.1' or add 'click==8.2.1' to your requirements/pyproject.toml dependencies. Alternatively, upgrade to BentoML version with PR #5480 merged which handles Click 8.3+ compatibility. Verify the containerization works by running 'bentoml containerize <service_name>:latest' after downgrading.
