PowerApps: Error code 502 – The server did not receive a response from an upstream server

Working on PowerApps project and integrating with PowerAutomate (Flow) to perform some update on SharePoint List. The PowerApps thrown error as screen shot below.

Error Code 502 – The server did not receive a response from an upstream server.

WorkFlowName.Run failed: { “error”: { “code”: 502, “source”: “asia-001.azure-apim.net”, “clientRequestId”: “a1dd8bf2-cfba-465b-89d5-25c8f380a974”, “message”: “BadGateway”, “innerError”: { “error”: { “code”: “NoResponse”, “message”: “The server did not receive a response from an upstream server. Request tracking id ‘08585434596297091463243902025CU13’.” } } } }

When check in flows’s history, the status show succeeded and data is updated into SharePoint list without issue.

Tried many ways and tips from community like below:
 – Export and Import as new flows
 – Re-create the same flows
 – Change sharepoint list’s column data type
 – Change data input of PowerApps flow 
 – Etc …
There is no impact to the PowerApps functionality but Bad user experience to customer when using the PowerApps. 

Thank you to my peer Nimesh who help to resolved this issue. What he did was added return a response back to PowerApps. And that’s it simple trick. 

If you are facing the same error please give it a try.

Recommended to have this as a practice to always return a response back to PowerApps in the flows.

Hope this will save your time for troubleshooting.
