Header: Content-Type: application/json-patch+json doesn't work

Hello everyone,

I think Copilot Studio doesn't correctly interpret or replace the original Content-Type of an HTTP request.
I'm trying to update a card with a PATCH request, but this PATCH requires Content-Type = application/json-patch+json. I've changed it, but the request returns a 415 error "Unsupported Media Type". I've tried it in Postman, and it works fine. Do you know what I can do to update it correctly?

Thanks in advance.

That is strange, I will see if I can reproduce this.

In the meantime have you tried using a cloud flow instead as a workaround? Via that flow you should also be able to use the same HTTP request in a Send an HTTP request to Azure DevOps action and use the same URI and payload.
