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.
