create sharepoint item error code 502



I am attempting to create a sharepoint item from a query (azure dev Ops) using Microsoft flow.

I have received an error for one of the items. All other items created ok.


Error code is 502

"message": "The response is not in a JSON format.",
    "innerError": "HTTP Error 503. The service is unavailable

Any help would be appreciated.


Hey @Anonymous 


Can you share more details on the flow and the error? Possibly a screenshot? Can you check if there were all values provided to the required fields in the create item action (ensuring no Null value was provided or no mismatch of datatype was there)?


Hope this Helps!

Hello @Anonymous,


If you try to re-run the flow for that particular item, will you get the error again?

What difference exists between this item and the others?
