I have an AWS Amplify application (next.js, node v16.18.1) with two builds (dev & prod branch). One week ago the prod build failed with the following error message without any code being modified:

!!! CustomerError Framework Web not supported

The dev build still works. To check I've created a branch from dev called test and ran a build. This build failed with the same error as above.

There a no warnings or such in the AWS Amplify build log.

I've deleted the AWS Amplify app, created a new one resulting in the same error. I've deleted individual builds in the AWS Amplify app all resulting in the same error for the prod or test branch (which is a clone of the dev branch) while dev is building successfully in all scenarios.

It appears the branch is mistakenly being detected as web which is what is used for applications that use frameworks like React or Angular. Try running this command to update your branch's framework to Next.js - SSR:

aws amplify update-branch --app-id <value> --branch-name <value> --framework 'Next.js - SSR'
