I'm having a similar issue with the business connector as well. Useless error appears after the flow is stuck for about 15 minutes:
Edit: (similar issue as this is a 504 and not a 502 response)
{
"error": {
"code": 504,
"source": "flow-apim-europe-001-westeurope-01.azure-apim.net",
"clientRequestId": "xxxxxx",
"message": "BadGateway",
"innerError": {
"status": 504,
"message": "Request to Graph API has timed out.\r\nclientRequestId: dfghfdgh\r\nserviceRequestId: sdfdsfsdfs;dfsdfsfsd;dfghdfghgfd",
"error": {
"message": "Request to Graph API has timed out."
},
"source": "excelonline-we.azconn-we.p.azurewebsites.net"
}
}
}
I guess there is something up with the table in that file, another file with the same table works fine, so there is probably the content of a cell that is causing this. But I can't do much when all I have is the rather useless error above 😕
Any suggestions?
