Antigravity Agent always returns HTTP 500 Internal Server Error

Hi, I’ve been experiencing persistent HTTP 500 errors in Antigravity since yesterday.
The error occurs with all models (Gemini 3.1 Pro, Claude Opus 4.6, GPT-OSS).

Error: HTTP 500 Internal Server Error
Message: “Internal error encountered.”

Sample TraceIDs:

  • 0xe973bd7ea
  • 0x676ad53f6
  • 0x21cca2945

Account type: Ultra
Platform: macOS
Started: ~March 31, 2026

Any help appreciated.
