Gemini 3.0 Pro preview with empty response.text

[Bryan_Hughes]

This is really just a continuation of:

Gemini 2.5 Pro with empty response.text

Running Gemini 2.5 Pro with grounded search sometimes returns empty response.text with finish_reason of STOP and no other reason. When I inspect the response dict it shows evidence of the search with some web meta information, but nothing else. Any ideas on what is going on? Here is my code: def get_response(seed, model, system_prompt, user_prompt): api_key = os.environ.get('GEMINI_API_KEY') google_search_tool = Tool( google_search=GoogleSearch() ) response = None …

This issues is not only present in 3.0, but my retry work-around no longer works. I am working with our account team and will post any findings.

The key here is that response.text and response.candidates are None, along with most of the other fields. Was really hoping this would just go away but seems it just got worse.
