Nextjs Server Action is not working on hosting

[OhDavit]

[REQUIRED] Environment info

firebase-tools: 13.0.2

Platform: macOS

[REQUIRED] Test case

Deploying Next js app with form and server actions

[REQUIRED] Steps to reproduce

• Create an application next js app with npx
• Add React form and Server Action as a form handler(onSubmit)
• Initiate firebase project within the existing next js app
• Deploy to hosting
• Go to the page web.app.mydomain.com/discovery, fill the form and click on submit button

[REQUIRED] Expected behavior

Should work exactly as in the emulator, i.e. pressing Submit button calls backend function(server action) which does process request.

[REQUIRED] Actual behavior

Pressing Submit button doesn't call backend function(server action)

I am seeing the same exact issue.

firebase-tools: 13.0.3
firebase-frameworks: ^0.11.2
next: 14.0.1

The app behaves as expected when run on firebase emulators but not when deployed to hosting. SSR function is generated in both emulators as well as deployment.

Thank you for your efforts.
