Current Behavior

Hello FlutterFlow Team,

I am encountering a persistent build error when trying to run Test Mode. The app fails to load, and the developer console shows '500 Internal Server Error' and multiple 'Script error' messages for core Flutter packages.

We have already tried the following debugging steps:

Re-compiling all custom functions.

Starting new test sessions with a hard refresh.

Rebuilding the page from scratch on a brand new project.

Simplifying the backend query to a single document read with no filters.

The error persists even on a very simple page with a TabBar and a single backend query, which indicates a potential issue with the build environment for this project.

Thank you.

Expected Behavior

To load

Steps to Reproduce

Fire base in a tab
