Howdy!

How do we ensure that the “Build with AI” uses a particular LLM?  
When using Google Gemini as the default LLM in our system im getting the error: Invalid JSON payload received. Unknown name “additionalProperties” at ‘tools[0].function\_declarations[5].parameters’: Cannot find field

Thanks!
