https://github.com/72L/failed-to-find-server-action

To Reproduce

1. Deploy repro repo to Heroku app: heroku git:remote -a [your-app] and git push heroku main
2. Test that it works and keep this tab open (do not refresh)
3. Make an insignificant change (i.e. modify the readme or add a space)
4. deploy to heroku again git push heroku main
5. Do not refresh tab from step 2!
6. After successful deploy, test the app. The server action is now unresponsive.
7. Look into logs and see something like this:

Current vs. Expected behavior

I would expect the outcome of step 2 to be the same as the outcome of step 6.

Additional context

It does work on Vercel, but not Heroku. I've tried some ideas from #58431 but none of them solved this issue.
