The action uses the soon deprecated set-output command

[pcaversaccio]

Example warning here:

Warning: The `set-output` command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

Would appreciate if you could update the action accordingly.

This is already using 1.10 of actions/core. The warning is caused by backward compatibility. See actions/toolkit#1336.

Thx for the link. So it seems as this action somehow evaluates GITHUB_OUTPUT to empty? See comment here.

[zgosalvez]

Adding a little bit more context for future reference: actions/toolkit#1218 (comment) as GITHUB_OUTPUT is indeed not set. However, I'm not doing anything special in this action as I am setting output values as per current docs using the official @actions/core package:

• https://github.com/actions/toolkit/blob/main/packages/core/README.md#inputsoutputs
• https://docs.github.com/en/actions/creating-actions/creating-a-javascript-action

I'll re-open this issue for future visibility. Thank you!

Very interesting - maybe their docs are slightly outdated? I'm not a GitHub Actions expert tbh; maybe you can ask this question in the actions/toolkit repository since I assume others are also affected by this issue?

good news @zgosalvez, by bumping the zgosalvez/github-actions-report-lcov action to v4 the warning disappeared. I will close this issue accordingly.
