Conditional on a job fails if double quotes are used

Describe the bug Using double quotes in a conditional for a job results in

The workflow is not valid. <file_path>: Unexpected symbol: '"workflow_dispatch"'. Located at position 22 within expression: github.event_name != "workflow_dispatch"

To Reproduce Steps to reproduce the behavior:

1. Create a job with a conditional

test-job:
    name: Use double quotes
    if: github.event_name != "workflow_dispatch"
    runs-on: ubuntu-latest
    steps:
      - name: Checkout repository
        uses: actions/checkout@v2

1. Run it
2. See above mentioned error
3. Use single quotes instead if: github.event_name != 'workflow_dispatch', it works

Expected behavior Job should pass regardless of type of quotes used

GitHub Actions only support the use of single quotes for strings in expression language, not double quotes (see docs). This is an intentional limitation (at least for now) and is not something that can be fixed in the runner application. Therefore, I’m going to close this issue, and you feel free to create a feature request on the GitHub Community Support Forum which is actively monitored. Using the forum ensures that we route your feature request to the correct team. 😃

@drecali I’m aware that the documentation mentions only single quote is valid (after the fact, of course). However, I think that behavior is not intuitive, since double quotes are valid throughout the rest of the YAML syntax. Unless there is a good reason not to support double quotes, it should be fixed.
