502 error



I'm using OneDrive services with MS flow, and I have a few flows with the "when a file is created" trigger. I get an issue saying there is an issue with the flow's trigger. The details reveal that the service is unavailable - is something down right now?


This was working fine on Friday, and when I came back to work today, I got these issues.

Re: 502 error

Hi @Anonymous ,


It seems that there is a temporary problem with the service. Have you tried reconfiguring a similar Flow to see if a similar problem exists?

I can't reproduce a similar issue here. Please try reconfiguring the connection and checking if Flow is working.

MS Flow support released a message saying that the service has a temporary problem and it has been resolved. Please check if it affects you.

Re: 502 error

Hello - I've been receiving this problem too: "502 bad gateway". This happened yesterday as well as today again. In my case I'm adding information to an Excel file in my OneDrive with flow. If I go to try to create a new one I'm unable to link to the table in my Excel document (this is where the bad gateway comes in). It seems Flow isn't talking to OneDrive properly. Hopefully it'll be fixed soon...

Re: 502 error



Same problem here. Since yesterday, my flow failed with error "BadGateway". Although nothing was changed.

The error occurs on the action where I create a new row in an Excel table on Onedrive.


Error information:

{"error": {"code": 502,"source": "","clientRequestId": "da2b3987-9a83-4754-9bd4-21f91a8a1fef","message": "BadGateway",

"innerError": {"status": 502,"message": "Graph API is momenteel niet beschikbaar.\r\nclientRequestId: da2b3987-9a83-4754-9bd4-21f91a8a1fef","source": ""}}}


Re-creating this flow is a lot-of work. Importing (for re-creating a new flow) did not work.

Any suggestions?  Should I wait? Was there an update from Microsoft?
