How do I trigger a Github Action on project card movement?

Question

I need a Github action which closes an issue when that issue is moved to a "Done" column on a Github Project.

My issue is that the project_card trigger only works on "classic" projects. Github specifies this in their documentation for the project_card trigger: "This event only occurs for projects (classic)."

I would use a classic project, but unfortunately Github has made it so classic projects cannot be created for repositories unless that repo has an existing classic project. I assume this is to phase out classic projects, which is fine except for triggers like project_card which only work with them.

Hoping there is some form of solution for project_card trigger to work with non-classic Github projects in the interim?

I tried using this Github Action with a non-classic project, but the action uses the project_card trigger which led me to this issue.

Answer 1

I know this question is old and unfortunately this answer is a non-answer.

I recently ran into this issue, since GitHub now disabled creating classic projects. You're right, it looks like the new projects do not trigger project_card like classic projects did. In my opinion, this is a huge overlook on GitHub's part. I have opened a discussion about it: https://github.com/orgs/community/discussions/62113
