I'm using the HTTP Request Trigger to sync. data with a SaaS.

They get the URL and use it as a webhook endpoint to send event based data.

Previously they send the data with a "Content-Length: xyx" and the payload body -> it worked perfectly.

They changed now the way they send the payload body by not sending the "Content-Length: xyx" header and rather a "Transfer-Encoding: chunked" header.

With this new header Power Automate can not process it anymore and automatically sets a "Content-Length: 0" and hence removes the body.

Is there a way to support that by configuration?

I saw a similar complain on Stackoverflow, but with no answer: https://stackoverflow.com/questions/78767598/empty-request-body-in-microsoft-power-automate-from-datadog-notifications

I faced the same issue https://community.powerplatform.com/forums/thread/details/?threadid=61545ebe-532f-486d-8f62-0d9ccbd20077

There seem to be problems with basic network standards :(

Hi,

Can you please share a picture of the Connector you are using in your flow.

Right now the issue is, the standard Triggers do not support Chunking, which is what they are asking it to do.

So I want to verify which one you are using.
