I'm getting the above error in a Flow with the Approval Start and wait for Approval shape. I create a simple flow that waits for a SharePoint list item to be created or change and then just the Approval Start and wait for Approval action.
In Outlook (web browser), when I click Approve or Reject I get "The remote endpoint returned an error (HTTP UnsupportedMediaType). Please try again later."
It looks like the HTTP POST is going to the below URL. Hope this helps.
Solved! Go to Solution.
Hi @bogeorgethreewi ,
Thanks for your feedback.
I did a test on my side and I can reproduce such an issue.
It seems that Approval request works in Edge, and the test results in Chrome and Firefox are the same as you described.
I will report this issue on my side, if there are any updates, I will post back.
Yep also getting the same - this is the same issue reported by @Anonymous here: https://powerusers.microsoft.com/t5/I-Found-A-Bug/Approval-behaviour-has-changed-duplication-approval-request/m-p/299455#M4567
