Only the default branch 'refs/heads/null' is supported after #68 landed

[ChrisCarini]

Hello, I am getting the below error after #68 (fix for #66) landed and was picked up by my workflow:

Event file: /github/workflow/event.json
Event name: schedule
Ref: refs/heads/master
Private repository: null
Publication enabled: true
Format: sarif
Policy file: /policy.yml
Default branch: refs/heads/null
refs/heads/master not supported with 'schedule' event.
Only the default branch 'refs/heads/null' is supported

(ref: link)

This is happening on the scheduled runs of the workflow I have configured.

@laurentsimon - when you have a moment to take a look, could you help investigate? The repo in which this is run has the default branch set to master.

Thank you!

Thanks. I think I know what's happening. The schedule trigger does not seem to have a default branch, which is unexpected from me. I'll work on a fix.

cc @naveensrinivasan let's add better unit test for the action.

[laurentsimon]

fyi, I've created a support ticket with GitHub.

[ChrisCarini]

Awesome, thank you @laurentsimon !

@laurentsimon - it's late for me, so perhaps I'm just missing something obvious because I am tired, but I just noticed this action failed again for me for the same reason: https://github.com/ChrisCarini/environment-variable-settings-summary-intellij-plugin/runs/5040554515?check_suite_focus=true

I have the action pinned to b614d455ee90608b5e36e3299cd50d457eb37d5f, which I believe is the commit after the fix here (which, I confirmed worked as expected when testing... 🤔 ).

Any ideas? This seems very strange to me, so perhaps I am missing something right now..

[laurentsimon]

You're not missing anything, see #84. Looks like GITHUB_REPOSITORY is empty/not set on schedule triggers, which is unexpected. I'll update the #84 once we have a lead. Sorry about that.

[ChrisCarini]

SGTM, and no worries! Appreciate you looking into this (and #84 😄 )!
