call id: c14b5237-9700-446e-a72e-ec3cf4877649 I am getting the error

An error occurred in this call: pipeline-error-google-llm-failed

while executing this part of my prompt

8. Make the booking using the CreateAppointment with the values provided by the user.  
9. If the booking is successful, politely inform the caller that the booking is complete and indicate the call will now end. End the call using the endCall tool after speaking the end call phrase.

i can see tha the tool call executed succesfully but the call doesn't end with the call phrase

Hi there! I see you're having an issue with the

endCall

tool failing after a successful

CreateAppointment

tool call. Based on the error message

pipeline-error-google-llm-failed

, this could be happening for a few reasons: 1. **Quota or Rate Limiting Issues**: Your Google API key might be hitting rate limits, especially if you're making multiple calls in quick succession. [This has been reported by other users](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1343704609096601693). 2. **Timing Issues**: The

endCall

function might be called before all necessary prior interactions are complete. [Some users have experienced similar issues](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336719759965687923). 3. **Message Formatting**: The LLM might be expecting a specific structure that isn't being followed after the tool execution. Here are some troubleshooting steps you can try: - **Check your parameters**: Ensure the

endCall

tool is receiving the correct parameters:

json
{
  "callId": "your-call-id",
  "reason": "Appointment booking completed"
}

- **Verify configuration**: Make sure

endCallFunctionEnabled

is set to true in your dashboard configuration. - **Review your prompt**: Try adding a slight delay or additional confirmation step between the

CreateAppointment

success and the

endCall

execution. - **Inspect logs**: Look for any specific error details beyond the general pipeline error. If you continue to experience issues, collecting specific call IDs and detailed error logs would be helpful for further troubleshooting.

cc-ing @Mason to help you @Raju

It looks like the error occurred because the system expected a simple text string, but an object was provided in the

text

field. To resolve this, we need to update the payload so that the

text

field your function is returning contains a string, not an object. Let me know if you'd like help making that change!

@Mason yeah sure, would appreciate your help. what do i need to do to make that change

Sure absolutely, you would need to go into the server that your tool is hitting and adjust it to return valid text, not an object. Could you go in and confirm that?
