AI Studio Build Agent repeatedly returns "Invalid argument" error for 4 days

Hello Google AI Studio Team,

I have been experiencing a persistent issue with the Google AI Studio Build Agent for the last 4 days.

The Build Agent was working normally before this issue started. I was actively developing an Android application and the project was progressing successfully. However, for the last 4 days, almost every command now fails with an “Invalid argument” error.

The issue happens even with very simple commands that do not require any code modification.

I have already tried:

  • Different prompts/commands
  • Different Gemini models
  • Simple read-only project inspection commands
  • Retrying the request multiple times
  • Starting commands again after previous failures

The behavior is consistently similar:

  1. Send a command to the Build Agent.
  2. The agent appears to process it for several seconds.
  3. After approximately 10 seconds, the operation stops.
  4. The status changes to “Ran for 0s”.
  5. It then shows “Invalid argument”.
  6. The project remains inaccessible to the Build Agent for further work.

This is especially concerning because the application was already substantially built before the issue started. I do not want to recreate the project or make unnecessary changes to the existing files because the problem appears to be with the Build Agent rather than the application code.

Please investigate whether there is currently a server-side, Build Agent, project-session, or tool/API issue causing these repeated “Invalid argument” failures.

I would also appreciate confirmation of whether existing projects affected by this issue are safe and whether there is a recommended workaround.

Thank you.

Hello @Arshyan_Ali ,

Thank you for sharing this.

Would it be possible for you to try to restore your app to a previous version and verify if the app is working?

  1. Open the Version history tab in the right-hand panel of AI Studio Build Mode and test reverting back to a checkpoint prior to when the error first started 4 days ago.

Please reach out to us if this does not resolve the issue.
