API workflowinstances

I am trying to gather information of WF that generate the following error: Could not find active RDP session within specified time

URL being used is: https://t4.automationedge.com/aeengine/rest/workflowinstances

Filter applied:
{
“filter”: {
“columnName”: “createdDate”,
“displayName”: “Created”,
“columnType”: “date”,
“visibility”: false,
“comparator”: “eq”,
“valueSet”: [ “2024-07-05” ],
“error”: {
“hasError”: true,
“message”: “Could not find active RDP session within specified time”
},
“disabled”: true
}
}

Content-Type : application/json
X-session-token : Generated before the call

Return I get is:
{
“message” : “Bad Request”,
“success” : false
}

Where do I get it wrong?
