We have a flow set up to listen to a list in SharePoint. Whenever a list item is added or updated, the flow triggers. The ONLY item in the flow is an HTTP POST call configured as shown below. The body is a 42 line JSON object.

When the flow is triggered, we are seeing two errors, shown below:

Tested the target URL with a Postman call and an identical body and the call was successful and things functioned as expected.

What are these errors? How do we debug this?

Re: Outgoing HTTP Post Fails w/ ReceiveFailure and Error While Copying to Stream

Hello @bbelman

Did you find a solution to your issue or is it still relevant?

I noted that you did not specify that the content is json. Add a header (key/value) "content-type"/ "application/json" and try again.

Let us know how it went

Kind regards, John
