query_by_wiql throws exception

query_by_wiql throws exception:

'Unable to build a model: ("Unable to deserialize to object: type, AttributeError: 'str' object has no attribute 'get'", AttributeError("'str' object has no attribute 'get'")), DeserializationError: ("Unable to deserialize to object: type, AttributeError: 'str' object has no attribute 'get'", AttributeError("'str' object has no attribute 'get'"))', DeserializationError("Unable to deserialize to object: type, AttributeError: 'str' object has no attribute 'get'", AttributeError("'str' object has no attribute 'get'")))

I'm trying to get a list of backlog items ids using the following function:

def get_backlog_item_ids(self, project_name, item_type="Product Backlog Item"):
try:
work_item_tracking_client = self.connection.clients.get_work_item_tracking_client()
wiql_query = f"""
SELECT [System.Id]
FROM WorkItems
WHERE [System.TeamProject] = '{project_name}'
AND [System.WorkItemType] = '{item_type}'
ORDER BY [System.Id]
"""
query_result = work_item_tracking_client.query_by_wiql(wiql=wiql_query)
work_item_ids = [item.id for item in query_result.work_items]
print(f"Retrieved {len(work_item_ids)} backlog item IDs from project '{project_name}'.")
return work_item_ids
except Exception as e:
print(f"Error retrieving backlog item IDs: {str(e)}")
return []

Comience en el punto de entrada query_by_wiql del cliente de seguimiento de work items y reproduzca la excepción con el WIQL mostrado en el issue. Compruebe la forma esperada del argumento wiql y verifique que la consulta devuelve IDs de work items sin un error de deserialización.
