I have a Flutter Web project, up to version 12.4.0 by enabling web frameworks experiments I was able to deploy to Firebase hosting correctly.

By upgrading to 12.4.2 instead, the deploy or the firebase init with the same configuration gives me:

firebase deploy --only hosting           
Could not determine the web framework in use.

Error: Unable to detect the web framework in use, check firebase-debug.log for more info.

I also tried with version 12.4.1 and it gives the same problem. By downgrading to 12.4.0 everything goes back to working properly.

Hi @g-adorni-neting, thanks for reporting this issue. I was able to reproduce this. I encountered the same error when using v12.4.2 and v12.4.1 as you mentioned. After downgrading to v12.4.0, I was able to run firebase deploy without any issues.

Let me notify our team about this so that they can investigate.

I experience the same issue in v12.4.3, but downgrading to v12.4.0 did not fix it for me.
Also downgrading to 12.3.1, than 12.2.1 and 12.1.0 did not fix it for me, I get the same error as g-adorni-neting.

The weird thing is that firebase-debug.log disappears when the deploy script exits, so I can't even see the detailed logs to provide more info.

note: the command worked for me until the latest update, maybe I miss a cache clearing step when downgrading? 🤔

Related:
When doing a firebase init hosting, and then pointing it to your Flutter app, the warning "Could not determine the web framework in use.", and a choice of web frameworks appears, but no choice of Flutter Web can be seen.

Easy to reproduce:

mkdir firebasetest
cd firebasetest
flutter create hosting --platforms web
firebase init hosting
<run through the steps>

EDIT:
This is using v12.4.4

Rolling back to v12.4.0 seems to fix it: The above reproduction finds a Flutter project this time.

Could this be related to 17eb321 ? This commit was added shortly after 12.4.0 was released, and, as far as I can see, is the only web-frameworks related commit since.

For anyone still affected by this:
I had the same issue, using Firebase CLI 12.4.7 and downgrading to 12.4.0 didn't help. My firebase.json was configured according to "Change your hosting config in firebase.json to have a source option, rather than a public option.". Once I changed source to public in firebase.json the project deployed without any problems.

I'm experiencing the same issue, but with Next.js framework. I can't resolve it with the latest version, and as mentioned in this discussion, version 12.4.0 works for me as well. For now, I can proceed, but I would like to see a solution to this problem.

mac: 13.4.1
node: v20.6.1
npm: 9.8.1

@andreasgrossmann yes, you are right. documentation is out dates and CLI also generates source by default.
