Environment info

firebase-tools: 12.7.0

Platform: Ubuntu 22.04.3 LTS

Test case

I'm starting a fresh project with GitHub and the Next.js framework integration. I started from scratch this morning, and everything went well. I was able to deploy from my local machine and hosting picked it up.

Steps to reproduce

1. I pushed to GitHub to make sure the integration was working and got the following error:
   

2. I added the env variable and pushed to master:
   

3. I got another error:
   

Could not determine the web framework in use.

4. I tried switching the hosting.source key to hosting.public in firebase.json. That got rid of the error, but then my site didn't deploy. I got the dreaded "index.html missing" error page.

Expected behavior

I expected the GitHub deploy to work first try without any intervention, as I was using the default firebase init workflow.

Actual behavior

I got a series of two different errors in my GitHub Actions as described above ☝️
