Question

You maintain a JavaScript action that reads files from the caller's repository working directory. Users report that when they reference your action with 'uses: your-org/format-check@v2', it fails with an error indicating the target source files cannot be found, even though those files clearly exist in the caller's repository. Your action.yml correctly specifies 'runs.using: node20' and 'runs.main: dist/index.js', and your compiled bundle is committed. What is the MOST likely cause the users must address in their workflow?

Accepted Answer

The workflow job is missing an 'actions/checkout' step before the step that invokes your action, so the repository contents are not present on the runner.

Answer

The action needs 'runs.using: composite' instead of 'node20' in order to access the caller's files.

Answer

The users must set 'permissions: contents: read' on the job for the action to read repository files.

Answer

The action must declare the source files as inputs in action.yml before it can access them at runtime.
