Hey @ben-of-codecraft ! Thanks for identifying this bug. I noticed you are using it with the app and that error message is coming from there, however you have no-backend: true set in the action argument. Is this argument intended or you wanted to remove it?

I think we should throw an error earlier if the flag no-backend is set yet the workflow dispatch event invoked digger. If you remove that flag and confirm it works we can ship a fix for this particular case

@motatoes retested this today. The cause was the dispatch with no-backend = true. If you change it to PR workflow and no dispatch, it does work fine, as you pointed out.

Thanks for looking at this.

I think an earlier error that helps users know what is causing the problem would be great.
