Test Mode crashes with 500 Internal Server Error

Troubleshooting
Resolved

Hi everyone, I'm running into an issue with Test Mode in FlutterFlow.

Whenever I try to launch Test Mode, it gets stuck at "Waiting for debug data", and the DevTools console shows this:

GET https://debug-service-frontend-free-xxx... β†’ 500 (Internal Server Error)
Script error involving: flutter_flow/ext_form_field.dart, icon_button.dart, etc.

What have you tried so far?

Here’s what I’ve tried so far:

- Cleared build cache

- Used multiple browsers (Chrome, Safari, Edge)

- Created a brand new project with just a Text widget

- Run Mode works fine(partly), but Test Mode always crashes

Additional info:

- On a different computer, Chrome has the same error, but Safari does work β€” although it somehow fails to connect to Firebase there.

- On my main computer, both Chrome and Safari produce the same error and Test Mode does not work at all.

Any ideas or is anyone else experiencing this? Thanks in advance!
