Greetings,
I've been using my AP Approval Workflow for a couple of weeks with no issues, however, I made a few changes to one of the SharePoint list that the flow is attached to and then I started to get the BadGateway Error.
Here's my original flow:
I have a SharePoint list called Departments and here is where I made some changes, specifically in the Approvers Text Columm, I changed email addresses:
Here are my flow run fail details:
Here's the error code:
{
"error": {
"code": 502,
"source": "canada-001.azure-apim.net",
"clientRequestId": "bc66974c-56f2-483f-a8bc-7776c4dddd51",
"message": "BadGateway",
"innerError": {
"status": 500,
"message": "Cannot deserialize the current JSON object (e.g. {\"name\":\"value\"}) into type 'System.Collections.Generic.IEnumerable`1[Microsoft.SharePoint.Connector.SPListExpandedReference]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.\r\nTo fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List<T>) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.\r\nPath 'Value', line 2, position 11.\r\nclientRequestId: bc66974c-56f2-483f-a8bc-7776c4dddd51\r\nserviceRequestId: bc66974c-56f2-483f-a8bc-7776c4dddd51"
}
}
}
Any help would be greatly appreciated.

Thanks Trond Aarskog !! 🤜🤛
Hello @RaulAG,
In reviewing your post there seems to be an issue with the value that you are updating in the SharePoint List. It seems the action item you are referencing appears to have some property type issues.
Have you tried deleting the Approve Updated item action and recreating it since you’ve updated the list?
If not, I would recommend deleting the action and recreating it. It’s looking for an array of items but is only returning a single item not affixed in a type array.
Hope this helps 😊
Regards,
Kristie
