query_async is not working

[DiarmaidEverycs]

PyOrient Version: 1.5.5 OrientDB version: 2.2.35

I am trying to asynchronously get records from the database, using the get_query_async() function. I have a very simple example:

`class testGraph(): def add_to_graphl(self, record): print("We succeeded in getting a record")

def get_from_database(self, client): """ client --> database connection returned by pyorient.OrientDB(database, port) query = """select from " limit = -1 fetchplan = "@*:-2" client.query_async(query, limit, fetchplan, self.add_to_graph) `

This is failing with:

pyorient.exceptions.PyOrientBadMethodCallException: <bound method testGraph.add_to_graph of <main.testGraph object at 0x7f5a0e2d3390>> is not a callable function
