[Bug] "Agent Terminated" error makes Antigravity COMPLETELY UNUSABLE on Google Workspace accounts - Personal accounts work fine

Summary

The recurring “Agent terminated due to an error” issue in Antigravity is exclusively affecting Google Workspace accounts (specifically Google AI Ultra for Business). Personal Gmail accounts — including free-tier accounts — are working perfectly fine with zero agent termination errors.

Critically, this is not an intermittent issue — the Workspace account is essentially non-functional. The agent terminates on nearly every interaction, and retrying does NOT resolve it. Retry briefly worked for only a few hours on one specific day, but otherwise the agent remains completely broken on Workspace accounts.

This distinction is critical for the engineering team to narrow down the root cause, as it strongly suggests the issue lies in how Workspace/organization-level authentication, tokens, or quota enforcement interacts with the Antigravity agent backend.

Environment & Account Details

Detail Workspace Account Personal Account
Account Type Google AI Ultra for Business (Workspace) Personal Gmail (free tier)
Agent Terminated Errors :cross_mark: Yes — on nearly every interaction :white_check_mark: None — works flawlessly
Retry Works? :cross_mark: No — agent keeps terminating on retry :white_check_mark: N/A — no errors to retry
Antigravity Version Latest (v1.22.2+) Same version
OS Windows Same machine
MCP Servers Disabled (ruled out) N/A

What Happens

  • On the Workspace account: The agent terminates with “Agent terminated due to an error” on nearly every interaction. Retrying does NOT fix it — the agent just terminates again. The platform is essentially unusable on the Workspace account. Retry only worked briefly for a few hours on one specific day, but has otherwise been completely non-functional.
  • On a personal Gmail account (even free tier): The exact same workflows, same models, same machine — zero termination errors. Everything runs smoothly.

Why This Matters

  1. It’s NOT a general platform issue — personal accounts are completely unaffected.
  2. It’s NOT a temporary/intermittent issue — the Workspace account is persistently broken, not just occasionally failing.
  3. Retry does NOT help — unlike typical transient errors, retrying just results in another termination.
  4. It’s NOT an MCP conflict — MCP servers have been disabled and the issue persists.
  5. It IS account-type specific — the only variable that triggers the error is using a Google Workspace (AI Ultra for Business) account.

This points to something in the Workspace authentication flow, token refresh mechanism, organizational policy enforcement, or quota handshake that is causing the agent session to terminate prematurely — and it is not recovering on its own.

Request to the Engineering Team

  • Please investigate the difference in how Workspace vs. personal account sessions are handled on the backend.
  • Workspace users are paying customers (AI Ultra for Business) and currently cannot use Antigravity at all, while free-tier personal accounts work flawlessly.
  • A previous post ([Bug] “High traffic” error causing agent termination 3-4x per session) was acknowledged and escalated by @Mrinal_Ghosh, but I want to make the severity and Workspace-specific nature of this bug explicitly clear — the product is completely non-functional on Workspace accounts.

Steps to Reproduce

  1. Sign into Antigravity with a Google Workspace account (AI Ultra for Business).
  2. Start any agent task (coding, research, etc.).
  3. The agent will terminate with “Agent terminated due to an error” almost immediately.
  4. Click retry — the agent terminates again (retry does NOT work).
  5. Sign out and sign in with a personal Gmail account.
  6. Run the exact same task — no termination errors occur.

Thank you for looking into this. This is a blocking issue — Workspace accounts cannot use the product at all. Happy to provide logs, feedback reports, or any additional information to help resolve this.

Update - the v1.22.2 fix didn’t hold.

I was genuinely excited when v1.22.2 dropped because the agent actually worked for about a day. No terminations, smooth sessions, I thought it was finally fixed. But by the next day it was right back to the same thing - “Agent terminated due to an error” on every other interaction, sometimes every single one.

I’m still on the latest version. Nothing changed on my end. Same machine, same Workspace account (AI Ultra for Business), same workflows. The only variable that makes the error disappear is signing out and switching to a personal Gmail - then it works perfectly, every time, zero issues.

Today is actually one of the rare “good” days where the agent sort of works, but even now it’s not stable. It terminates, I click retry, it terminates again, retry again, and eventually it goes through. That’s not really “working” - you can’t code or do any meaningful work when you’re babysitting a retry button.

This has been going on since early March. Over a month now. Workspace users are paying customers and we’re getting a significantly worse experience than free-tier personal accounts. That shouldn’t be how this works.

@Mrinal_Ghosh - is this still being investigated? The escalation from the previous thread was appreciated, but it doesn’t seem like the root cause for Workspace accounts was actually addressed in v1.22.2. Would really appreciate a status update or confirmation that the team is aware it’s still happening.

Hi Muhammad,
This same thing is happening with me. I was excided since I have a workspace account because I believed antigravity will be smoother for me as I thought I have been Googles paying customer for a long time. But it is very frustrating to see agent terminated pop up like 10 times in a minute essentially rendering Antigravity worthless. I had to then spend money on claude and cursor too. For me Antigravity is not working well even on the personal id front. This is very disappointing.

[BUG] Agent Terminated Error on ALL Models — HTTP 503 — Fresh Accounts with 100% Quota Remaining

Description:
I am getting the following error on every single model available in Antigravity, right from the start — without sending even a single message:

“Agent terminated due to error. You can prompt the model to try again or start a new conversation if the error persists. See our troubleshooting guide for more help.”

Models affected:

  • Gemini 3.1 Pro (Low & High)

  • Claude Opus 4.6

  • Claude Sonnet 4.6

  • Every other available model

What I have already tried:

  • Signed out and signed in with a brand new Google account

  • Both accounts have 100% quota remaining — zero usage

  • Started multiple new conversations

  • Reloaded/re-ran onboarding

  • Disabled all extensions

  • Tried “continue” and “proceed” prompts in chat

  • Tried Restart Agent Service via Command Palette

None of these steps resolved the issue.

My conclusion:
Since the error appears instantly on fresh accounts with no usage, across every model, this is clearly a server-side issue (HTTP 503) and not related to quota, rate limits, or my local setup.:zany_face:
