Hey guys, I build a custom LLM server for Vapi that was working perfectly a week ago still. Now it is not working anymore and when I am looking into the logs I see the following: incoming-webhook failed validation. Errors: [ "property status should not exist", "property role should not exist", "type must be one of the following values: add-message, control, say, transfer" ] I am sending the response as a stream: chunk 1: { "id": "chatcmpl-wskstton73", "object": "chat.completion.chunk", "created": 1728280122, "model": "gpt-3.5-turbo-0125", "system_fingerprint": null, "choices": [ { "index": 0, "delta": { "role": "assistant", "content": "", "refusal": null }, "logprobs": null, "finish_reason": null } ] } chunk 2: { "id": "chatcmpl-wskstton73", "object": "chat.completion.chunk", "created": 1728280122, "model": "gpt-3.5-turbo-0125", "system_fingerprint": null, "choices": [ { "index": 0, "delta": { "content": "hello nice to hear from you" }, "logprobs": null, "finish_reason": null } ] } chunk 3: { "id": "chatcmpl-wskstton73", "object": "chat.completion.chunk", "created": 1728280122, "model": "gpt-3.5-turbo-0125", "system_fingerprint": null, "choices": [ { "index": 0, "delta": {}, "logprobs": null, "finish_reason": "stop" } ] } Thanks for your help! Any idea @Sahil?

Anything custom aside, I see

incoming-webhook failed validation. Errors: [ "property status should not exist", "property role should not exist", "type must be one of the following values: add-message, control, say, transfer" ]

in call logs even when running a trivial example right from the dashboard.

Could you help us here @Shubham Bajaj @User @Sahil ? 🙏

seems to be a sitewide issue then.

Looking into it.

looks good now

All good from my side too. Thanks!
