Non-fatal caching error with cypress/included in GitHub Actions with non-root user

[MikeMcC399]

Issue

If cypress-io/github-action is used to run cypress/included with --user 1001 (as recommended), then GitHub actions may report a caching error

Failed to restore: "/usr/bin/tar" failed with error: The process '/usr/bin/tar' failed with exit code 2

The workflow includes the following:

    container:
      image: cypress/included
      options: --user 1001

This problem does not occur the first time a workflow is run in a branch. It happens on subsequent runs when caches have been established.

The caching error does not prevent the action from successfully completing Cypress tests.

Workaround

Set the environment variable CYPRESS_INSTALL_BINARY=0 to avoid unnecessary caching of the Cypress binary. For instance:

  docker-included:
    runs-on: ubuntu-22.04
    container:
      image: cypress/included
      options: --user 1001
    steps:
      - uses: actions/checkout@v4
      - uses: cypress-io/github-action@v6
        env:
          CYPRESS_INSTALL_BINARY: 0

This setting should be added to the documentation.
