   I believe this may also impact other tools. Dropping some responses in case this is helpful:

   "responseBody": "[
     {
       "error": {
         "code": 400,
         "message": "Unable to submit request because function call `default_api:task` in the 2. content block is missing a `thought_signature`. Learn more: https://docs.cloud.google.com/vertex-ai/generative-ai/docs/thought-signatures",
         "status": "INVALID_ARGUMENT"
       }
     }
   ]"

   are you using gemini through google, zen, or openrouter. Because openrouter still has bugs on their end

   Ah, that may be related. Im accessing it through an internal proxy that my org has set up (similar to openrouter). Can look into during the week
