We should take a look at this announcement made by Github yesterday: GitHub Actions: Deprecating save-state and set-output commands | GitHub Changelog
We need to change the way we store variables in github actions.
So no more
echo "::set-output name=secret_answer::42" to store the variable
secret_answer that can be accessed by the following steps of a job.
I’ll have a read of the announcement and will create a patch to fix it in our actions soon.
