Unauthorized Error - The Response is not in JSON format

Today all of my flows started to fail randomly with this error.


The Response is not in JSON Format.  They are only failing when the "Get Items" portion of the flow is triggered.


This started happening around 230pm CST

Same thing is happening to my flows today that have been running for a couple of months without issue. Failures started around 10am PST. I am able to resubmit the failures and they go through on resubmit without issue. 

Not applicable

Same thing is happening to my flows and they started yesterday as well. It is happening with the "Update item " sharepoint action after the "start and wait for approval" stage from 8am bst

Same is happening to me in sharepoint flows.

I think the flows are back to working like they should be.  I have not had one fail since 6:30pm CST.  It appears that this was a microsoft issue

Same for me. One failed one hour ago. Please advise what the issue is !!

Capture.PNGHi there


We have the same issue - Flows fail the 1st time but we have a retry and the flows pass the 2nd time.


Looks like the headers maybe not being passed correctly?





The flows are back to not working again periodically. I am not sure what the issue but microsoft really needs to figure it out

someone HELP !

I would say use the contact us link at the bottom of this page and submit a ticket. More tickets hopefully will result in this getting fixed!
