Why is the release-action on Github not working?

I'm using the github actions release-action@v1 in my workflow, and it's not generating artifacts after signing the app and building the apk and app bundle.

I created a tag before pushing to the repository, but the action is still not working.

I think it's because am not passing a commit to the workflow.

What do I need to do there?

Solution

The action documentation states that:

You must provide a tag either via the action input or the git ref (i.e push / create a tag). If you do not provide a tag the action will fail.

Moreover, the tag input states:

tag: An optional tag for the release. If this is omitted the git ref will be used (if it is a tag).

Your issue is probably related to the push trigger you set in your workflow file, as it will not generate any git ref tag. And as you're not using the action tag input, the action can't identify the tag to use to generate the release.

You have 2 options here:

Remove the on push trigger. For the workflow, and consequently the action, only run if a tag is present.
Add the tag input to the action with the artifacts and the token inputs you're already using.
