Application builder Gemini malfunction

:red_exclamation_mark:Issue Summary:

I’m encountering a consistent error in Firebase Studio when using the Gemini AI assistant, especially when asking it for help with UI-related code changes.

Every time I submit a prompt (even simple ones like “test”), I receive the following error:

bash

CopyEdit

❌ Sorry, I hit a snag. Please try again shortly.
Unsupported Part type{"metadata":{"purpose":"${e}","pending":true}}

This happens regardless of the prompt content, and the error seems to be internal. I’ve tested with basic prompts, advanced prompts, and across sessions — nothing works.


:round_pushpin:Where it’s happening:

  • Inside Firebase Studio
  • In the Gemini AI assistant panel
  • While trying to use it to modify or analyze project files

:light_bulb: What I’ve tried:

  • Reloading Firebase Studio
  • Restarting the project
  • Simplifying prompts
  • Checking for service outages
  • Inspecting browser console (no obvious network failure)

:puzzle_piece: Suspected Cause:

It appears that the Gemini assistant inside Firebase Studio is referencing an unsupported or malformed metadata part type — possibly due to


a bug in the assistant’s backend or misconfiguration in message formatting.
