Using the HTTP connector in a flow in Power Automate, we are attempting to PUT changes to a third-party REST API. The query works without a hitch in Postman, but when attempting the same in Power Automate the service returns 415 Unsupported Media Type { "message": "Content-Type header should have application/json", "code": "invalid_content_type" }
We would have thought adding the header manually as per below would take care of it, but it continues to fail with the same message. Any suggestions?
