BUG: Persistent HTTP 500 Internal Server Error consuming credits in Antigravity

Corpo da mensagem (Copie tudo abaixo desta linha):

Hello team,

I am experiencing a persistent issue in the Antigravity IDE where the agent execution constantly terminates due to an HTTP 500 Internal Server Error.

This is happening across multiple different models, including Gemini Pro and Claude Opus, which indicates a backend/infrastructure failure rather than a prompt or model-specific issue.

Critical Issue: Even though the server fails to return a response and throws a 500 error, my credits are still being consumed/deducted for these failed requests.

Here are the debug logs with the Trace IDs for investigation:

Error Details:

  • Error: HTTP 500 Internal Server Error

  • Trajectory ID: 97e8512c-aa25-4213-9c28-425aa6b1d…

  • TraceID 1 (from recent log): 0x3f24bdb80e852…

  • TraceID 2 (from previous log): 0xea0b1dd9025d1…

Raw Sherlog Output: Headers: {“Alt-Svc”:[“h3=”:443"; ma=2592000,h3-29=“:443”; ma=2592000"],“Content-Length”:[“109”],“Content-Type”:[“text/event-stream”],“Date”:[“Fri, 08 May 2026 12:11:46 GMT”],“Server”:[“ESF”],“Server-Timing”:[“gfet4t7; dur=2584”],“Vary”:[“Origin”,“X-Origin”,“Referer”],“X-Cloudaicompanion-Trace-Id”:[“3f24bdb80e85249b”],“X-Content-Type-Options”:[“nosniff”],“X-Frame-Options”:[“SAMEORIGIN”],“X-Xss-Protection”:[“0”]}

{ “error”: { “code”: 500, “message”: “Internal error encountered.”, “status”: “INTERNAL” } }

Could you please investigate the server-side failure using these Trace IDs and refund the credits that were incorrectly consumed by these server crashes?

Thank you.

Antigravity become unusable, rather than giving the task to one of the model, we stayed retrying every prompt 10s of times to get single response !!
the problem i am Pro user, and if everyone are suffering from these issues i don’t see any logical reason to upgrade to Ultra anymore.

this my common error with 3.1 Pro (high)

None of models are working

I have been having receiving this message since last week and has stopped me from using Antigravity, it has just been burning tokens without outputting anything meaningful: Trajectory ID: dd95930f-c550-4a31-84f2-0a350e358a29

Hey All,

This error often happens intermittently, so please attempt to retry or select a different model from the model selector. If the problem continues, could you specify which model you are using when this arises? Also provide a sample prompt to reproduce the issue and the latest Trajectory ID for troubleshooting.

@Novely I am experiencing the exact same instant HTTP 500 server error across all models.

Out of curiosity, are you using a Business/Workspace account, or did you recently change your primary email domain? I just posted my full Trace IDs and HTTP Headers over here, as I strongly suspect this is a backend issue: https://discuss.ai.google.dev/t/ultra-business-account-http-500-internal-server-error-loop-after-domain-change/144783

Did you ever get this issue resolved on your end? Let me know if your setup is similar!
