I have a webhook that receives updates from Azure AI Speech when a batch transcription is complete and I am regularly getting Microsoft.AspNetCore.Server.Kestrel.Core.BadHttpRequestException "Unexpected end of request content.".
My function app is implemented in python, so the exception is thrown by the function runtime as it is decoding it for the http-trigger.
The function app is running on a Linux Consumption plan in West-Europe.

I'm sorry to hear that you're experiencing issues with your webhook. To investigate the issue further, could you please provide me with the following information.
- Could you please share the code snippet of your webhook implementation in Python?
- Can you share the exact error message that you're receiving along with any additional error messages that may be related to this issue?
- Also share the payload that you're sending to the webhook when you receive this error message?
- And please confirm if you have made any recent changes to your webhook implementation or if this issue has been occurring since the initial implementation?
With this information, I can better understand the issue and provide you with a solution.

1.The code is:
@bp.route("speech-completed", methods=["POST"]) async def speech_completed(req: HttpRequest) -> HttpResponse:But this code is not called when the error occurs.
- The exception message is:
Exception while executing function: Functions.speech_completed Exception binding parameter 'req' Unexpected end of request content.
And the stacktrace is

RithwikBojja 75 Reputation points Microsoft Vendor2025-02-12T04:55:53.8733333+00:00 Hi @Julian Kopka Heerup, Can you provide the full code you're using? Could you elaborate on this point "I have tested the endpoint myself, and it works fine. However, when it's called from Azure AI Speech, it doesn't seem to work." and How are you triggering/Calling it from Azure AI Speech, also provide configurations you are using.
Thank you!
