Hi,
Have a flow that was previously working (a few months ago), was idle and now when we run it we get this "Error 431 Request Headers Too Large". I have tried calling the API with Postman and everything works fine, but when we do the same request with Power Automate we get this error.
Any general tips? I have for instance cleared cookies and checked the request with Fiddler together with MS but no concrete answers as of yet.
It is triggered from a button in a Model driven app record where the GUID from the record is sent in. And does a POST call to a api with a token. And it all works in Postman with the same values/information.
