I have same problem. Even with new accounts same problem. Seems like even if you put the file into the prompt files section doesnt return anything. @User it seems it’s a regional problem, cause big part of the community have same issue.

I am experiencing same issue @Vapi

Can you tell me more about the exact issue because if people is facing same problem and it is a big issue and vapi is not responding in the community

Hey Saurabh, This issue has been resolved. It was caused by Google Gemini rate limiting on their end, which affected the query tool since it relies on Google infrastructure. What happened: Google imposed rate limits on Gemini models, causing the query tool to return HTML error pages instead of JSON responses. Status: Fixed as of Jan 21, 11:30pm PST. Google confirmed the issue was on their infrastructure. What to do: • Try your query tool again - it should work now • If you're still seeing issues, consider adding your own Google API key in Custom Credentials for more reliable performance Incident details: https://status.vapi.ai/incident/809181 Let me know if it's working for you now.
