Antigravity Agent Execution Termination Error – HTTP 429 RESOURCE_EXHAUSTED

Google Antigravity

Hi Antigravity Support Team,

I have been using Google Antigravity IDE regularly for code debugging, development, and correction. For the past 3–4 days, I have been consistently facing the following issue:

"Agent execution terminated due to error.”

The problem occurs even when I start a new conversation and send a very simple prompt such as “hello”, so it does not appear to be related to a particular project, codebase, or prompt.

I have performed several troubleshooting steps, including checking the configuration, MCP settings, installation, and usage/quota information, but the issue persists.
The debug information:

Trajectory ID: 16adafc1-3aa1-4f39-8394-a77*********
Error: HTTP 429 Too Many Requests
Sherlog:
TraceID: 0xc307632***********
Headers: {“Alt-Svc”:[“h3=”:443"; ma=2592000,h3-29=“:443”; ma=2592000"],“Content-Length”:[“139”],“Content-Type”:[“text/event-stream”],“Date”:[“Mon, 07 Sep 2026 04:24:17 GMT”],“Server”:[“ESF”],“Server-Timing”:[“gfet4t7; dur=758”],“Vary”:[“Origin”,“X-Origin”,“Referer”],“X-Cloudaicompanion-Trace-Id”:[“c30763*********”],“X-Content-Type-Options”:[“nosniff”],“X-Frame-Options”:[“SAMEORIGIN”],“X-Xss-Protection”:[“0”]}

{
“error”: {
“code”: 429,
“message”: “Resource has been exhausted (e.g. check quota).”,
“status”: “RESOURCE_EXHAUSTED”
}
}
I also tried the /usage command, but it results in the same Agent execution terminated due to error message.

My current environment is:
OS: Ubuntu Linux
Architecture: x64
Antigravity version: 1.107.0
Antigravity package: 1.23.2-1776332190
Installation: /usr/share/antigravity

I also verified that my MCP configuration is empty, so MCP does not appear to be causing the problem.

Could you please check whether there is an account-side quota, entitlement, backend capacity, or service-side issue associated with my account/trajectory?

I would appreciate your help in restoring the Agent functionality

I can provide the complete debug information, screenshots, or any additional logs required for investigation.

Hello, I’m experiencing a persistent issue with Antigravity where the agent terminates with an HTTP 429 RESOURCE_EXHAUSTED error.

I have already tried all the usual troubleshooting steps, including:

  • Uninstalling and reinstalling Antigravity
  • Restarting the application
  • Starting new conversations
  • Trying different models
  • Using a different Google account/email
  • Checking my quota/usage

My quotas are showing as available/full, but I continue to receive:

HTTP 429 Too Many Requests
RESOURCE_EXHAUSTED
Agent terminated due to error

My latest diagnostic information is:

Trajectory ID: 816ac467-f707-440d-91********
TraceID: 0xe23be2********

This issue persists even after changing accounts and reinstalling the application. Could you please check whether there is a backend, account, or quota-enforcement issue affecting my requests?

I would appreciate it if you could investigate this Trajectory ID and TraceID and let me know what is causing the 429 error, since my quota is still available.

Thank you.

Hello, I am encountering the backend quota desync bug where my active Gemini Ultra membership is not being recognized by the API gateway, resulting in false 429 errors. My local dashboard shows I have available quota, but the backend is blocking requests as if it is exhausted.

Could an somebody please manually resync my account?

  • Issue: HTTP 429 / RESOURCE_EXHAUSTED despite active Ultra subscription

Thank you.

I’m facing this problem too 2 days ago. I tried this solution I posted in another discussion and it worked: Pro account hitting 429 RESOURCE_EXHAUSTED despite quota showing available, persists after full reinstall - #2 by Adriel_Mederos_Matos

I hope it works same for you.

Hi Adriel,

Yes, that did work.

Thank you very much!
