Posted on by ari-cornish

Hello,

I have a Flow that runs an approval process for files in a SharePoint Online document library. My users have been using this Flow for months without issue until this week. All of the Flow's runs keep failing with the following error:

{

"error": {

"code": 502,

"source": "flow-apim-msmanaged-na-northcentralus-01.azure-apim.net",

"clientRequestId": "b536d691-d87a-4634-9154-fbaad4c10d54",

"message": "BadGateway",

"innerError": {

"status": 500,

"message": "Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))\r\nclientRequestId: b536d691-d87a-4634-9154-fbaad4c10d54\r\nserviceRequestId: b536d691-d87a-4634-9154-fbaad4c10d54"

}

I am an owner of the SharePoint site and Flow. Additionally, this is an Instant Flow. Has anyone know the best course of action to fix this error?

Thank you!

Hi @ari-cornish ,

Does your issue still exists?

If the error code 500 or 502 appears, the failure is temporary or transient. Click or tap Resubmit to try the flow again to see if the issue still exists.

You could refer to link below to troubleshooting the flow:

The error seemed to stem from the flow permissions. After going to manage run-users and selecting the SharePoint tab, I was able to give access to the corresponding document library and list.
