Google team, @Abhijit_Pramanik ,

Please can you advise if there is a broad outage or problem again?

I’ve been seeing the same error as many of the users posting above again since yesterday night on my Ultra account. Errors are:

“@type”: “type.googleapis.com/google.rpc.BadRequest”, “fieldViolations”: [ { “description”: “Invalid project resource name”, “field”: “name”

Please can you confirm this is a google-side error and expected fix time? If there’s anything that can be done my side to fix it too please advise.

This is crazy! Getting banned for over a day without any reason!
Why we have so many basic account verification problems?

helps no one.. according to Gemini it’s now a list of 15 different things that could be wrong. instead of collapsing the distribution probability we have now exponentially opened it up to a universe of possible problems..

Same exact error in my Antigravity. I have a paid Google AI Pro Account. With a Free-Test-Account it was working… I notied it 2 to 3 days ago.

Subject: Bug: Language server cannot read OAuth token on Linux – Invalid project resource name projects/

Environment

  • OS: Ubuntu Linux (x86_64)
  • Antigravity version: 1.16.5-1770081357
  • Installation: via official apt repository (us-central1-apt.pkg.dev)

Problem
After successfully authenticating via the Antigravity OAuth login flow, the language server fails to read the OAuth token and cannot retrieve the GCP project ID. Every agent request results in:

INVALID_ARGUMENT (code 400): Invalid project resource name projects/

Root Cause (from logs)
Two separate authentication systems are not communicating:

  1. The Electron app successfully completes OAuth login (confirmed in auth.log: “OAuth token changed”)
  2. The language server (server.go) cannot find the token (Antigravity.log: “Failed to get OAuth token: key not found”)

The language server appears to be unable to read the OAuth token stored by the Electron app in Local Storage (leveldb).

Steps to reproduce

  1. Install Antigravity on Linux via the official apt repository
  2. Log in with a Google account via the in-app OAuth flow
  3. Send any message to the agent
  4. Observe HTTP 400 error: Invalid project resource name projects/

Additional context

  • The same Google account works without issues on Windows (no GCP project configuration required)
  • Installing gcloud CLI and configuring application default credentials does not resolve the issue
  • gnome-keyring / libsecret is not installed by default, which may be relevant
  • The Electron auth flow completes successfully but the token is not accessible to the language server process

Relevant log excerpt (Antigravity.log)
E server.go:558] Failed to get OAuth token: key not found
W client.go:137] failed to set auth token
E log.go:380] agent executor error: INVALID_ARGUMENT (code 400): Invalid project resource name projects/

Facing same issue since 1 hr,
Getting this error

Trajectory ID: xxxxxxxx
Error: HTTP 500 Internal Server Error

TraceID: xxxxxxxx

Headers: ```json { “Alt-Svc”: [“h3=”:443"; ma=2592000,h3-29=“:443”; ma=2592000"], “Content-Type”: [“text/event-stream”], “Date”: [“Wed, 18 Feb 2026 17:50:04 GMT”], “Server”: [“ESF”], “Vary”: [“Origin”, “X-Origin”, “Referer”], “X-Content-Type-Options”: [“nosniff”], “X-Frame-Options”: [“SAMEORIGIN”] }

Same issue as above. “Agent terminated due to error”, HTTP 500 Internal Server Error in debug info.
For anyone having this, it might be worth copying the debug info and reporting. There is a “Report issue” option in the user menu in the top right of the IDE window.

The strange thing is, they told me there was a 5-day wait for the Claude renewal. I didn’t use it for around 7 days, but when I opened the app again, I only had 60% available with a 3-day reset timer. I don’t understand why, as I expected a fresh quota or at least a full 100% reset. This is ridiculous.

Here too, two days without being able to use Gemini Pro in Antigravity. What bother me the most is the issue is related just to Gemini Pro 3 (high/low), but if I select Gemini Flash, which I consider literally useless unless you’re using it only for reviewing or summarizing documents, Antigravity doesn’t give an error.

Claude Sonnet and Opus also work fine.

Pretty sure the problem it’s not account related because I can replicate the same issue with my personal account and with the account where I subscribed to Google Ai Pro.

99% of the time is a server-side issue (error 500), then there is nothing we can do. Just wait and pay for the time you don’t use the IDE… Nice.
A couple of months ago, it was possible to use the IDE with good results and, above all, with enough quota. They’ve drastically reduced the quota, and with every update, the bugs increase.

I’m wondering, how long will it be before they put Antigravity in the graveyard like they did with several other Google things?

Never had this type of issue with Claude code. I don’t think I’ll renew my subscription for Ai Pro.

Today I was able to use the Gemini 3 Pro, although it is extremely slow.

I’m starting to think the 500 error issues are related to the launch of the new Gemini 3.1 Pro model. It’s already present in the model list in Antigravity, but it’s not usable yet, at least for me. It says I need to update the software, but I don’t see any updates available.

In any case, Google demonstrates once again that it doesn’t care who pays for its service. A simple update on the ongoing problem would be better than silence.
