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 []

Start at the work item tracking client's query_by_wiql entry point and reproduce the exception with the WIQL shown in the issue. Check the expected shape of the wiql argument and verify that the query returns work item IDs without a deserialization error.
