Hi everyone,
I’m getting a persistent error whenever I try to send any message to the agent, even something as simple as “hi”:
Error: Agent execution terminated due to error.
Error IDs I’ve collected so far:
8a0be331-66dc-4d3c-8bc4-be7c80475604-8f0428455-6af9-447a-9e35-9a921e1c323c-872f22c18-385c-4313-8f38-6fc1f4e4f3c1-17
What I’ve already tried:
- Fully uninstalled and reinstalled Antigravity IDE (multiple times)
- Deleted
.antigravity-ideand.gemini\antigravity-ideconfig folders before reinstalling - Checked
mcp_config— removed a custom MCP server entry that was causing an unrelated “MCP Error” (fixed that one) - Signed out and back into my Google account
- Tried switching models (Gemini 3.6 Flash High and others) — same result
- Installed the “Google Data Cloud” extension from the Extensions panel
What I found while debugging via DevTools (Network tab):
SendUserCascadeMessage→ returns HTTP 200, but response body is empty{}- Following
GetInputCompletionrequests → also HTTP 200, but response body is empty{}as well - No errors show up in the Console tab
- No useful info in the crash logs under
.gemini\antigravity-ide\crashes(files are empty/0 bytes)
So it looks like the requests succeed on the network level, but something fails silently afterward, and the client just shows a generic “Agent execution terminated due to error” with no details.
I originally also hit a separate issue where the googlecloudtools.datacloud extension’s mcp_proxy_bundle.js file was missing (Cannot find module), which broke the built-in notebooks and visualization MCP servers — not sure if that’s related to the current issue or a red herring at this point.
Any idea what could be causing this, or how I can get more detailed logs? Happy to share more screenshots/logs if useful.
Thanks in advance!
