Transfer call error: call.in-progress.error-vapifault-worker-died I have transfer_call_tool in the vapi, now every time the assistant is going to transfer the call I am encountering ang error: Here is the error when I go to the call log: An error occurred in this call: call.in-progress.error-vapifault-worker-died Please help!

Thanks for sharing the error details. To help diagnose the issue, could you please confirm whether you are using a custom server URL for dynamic call transfers, and if so, is your server responding with a valid

destination

or

error

as required by the Vapi documentation? This will help determine if the error is due to a misconfiguration in the transfer tool or an issue with the server response. If you need immediate assistance, you can also contact [Vapi Support](https://docs.vapi.ai/support) with your call ID and account email.

Hello, no I am not using any, I am just using the simple transfer call in vapi Assistant > Tools > Predefined Functions Then input the phone number destination in E.164 format

Hey! To help track down this issue, could you share: - The call ID This would really help us figure out what went wrong!

Here are the sample call ids: - a8e076b5-a931-4b4c-85eb-ff1f8dfd2248 - 54dc847f-062a-416f-8cb3-16ed4f6761c8 - 5c0498f8-b61e-4341-8470-56bcc5b5e796 - f5c0ce67-68cf-48b9-a071-a9bdbf86e709 There are a lot of trials

Hey, this issue was on our side where a few of our workers died. Now you can try again, and you won't be getting this issue again. It's a rare issue which only happens if, at an uncertain point of time, there is an unexpected spike of requests.

I just had the same issue on two separate calls @Shubham Bajaj so it seems it's not fixed yet. Example: 6a8fafb4-fe6d-4474-88bb-52804788820e 7cdcdd66-c4b1-4d33-90e0-673f518884ba

Hey Floris, thanks for sharing the call_ids let me check with the team what can be done.
