- Failing step (command/step): [7/7] RUN bundle install --path vendor/bundle
- Exit code: 15
- Exact error message:
The `--path` flag has been removed because it relied on being remembered across
bundler invocations, which bundler no longer does. Instead please use `bundle
config set path 'vendor/bundle'`, and stop using this flag
- Missing packages or files mentioned: None reported (Gemfile was created earlier; no missing files noted)
- Version mismatch / related info:
  - Bundler version installed: bundler-4.0.8
  - The error indicates a Bundler CLI change: the --path flag has been removed; use bundle config set path 'vendor/bundle' instead

Remediation hint: Update Dockerfile to replace bundle install --path vendor/bundle with a Bundler path configuration, e.g., bundle config set path 'vendor/bundle' followed by bundle install.
