Problem
When tool output (e.g. from
webfetchor JSON schema files) contains keys like$ref,$defs,#, or/,tryParseJSONparses them into thefunctionResponse.responseobject.Google Gemini / Antigravity protobuf parser treats these keys as schema references rather than payload data, failing with:
{"error":{"code":400,"message":"The referenced name `#/$defs/Config` in function_response.response does not match to a display_name in the function_response.parts.","status":"INVALID_ARGUMENT"}}Solution
sanitizeFunctionResponseResultinopen-sse/translator/formats/gemini.jsto recursively sanitize forbidden schema characters ($,#,/,definitions) in tool result objects before constructingfunctionResponse.scripts/test-gemini-tool-response-sanitization.mjs.
