Query ContainsString not working

Request Type

Bug

Problem Description

When I try to make an api.find_cases call with a query containing 'ContainsString', I got an error message saying
{ "message": "JsResultException(errors:List((,List(JsonValidationError(List(Invalid query: unexpected {\"_wildcard\":{\"_field\":\"title\",\"_value\":\"*Vuln*\"}}),WrappedArray())))))", "type": "play.api.libs.json.JsResultException" }

Steps to Reproduce

1. Connect to API.
2. Set query to query = ContainsString('title', 'Vuln').
3. Call the API : siem_cases = api.find_cases(query=query).
4. Load the response as a json : a = json.loads(siem_cases.text).
5. Display the response with indent : print(json.dumps(a, indent=4, sort_keys=True)).
6. Run the script and you will get the error above.

I randomly tried query = Eq('title', 'vuln') and it looks like working idk why. Still resolved.
