Pymongo has removed authenticate method in Database class but log4mongo is still using it which cause exception.

I just install latest version of log4mongo which automatically installed pymongo as dependency. I got below error when instantiating MongoHandler :

TypeError: 'Collection' object is not callable. If you meant to call the 'authenticate' method on a 'Database' object it is failing because no such method exists.

Here is my code :

db_handler = MongoHandler(host=mongo_connection_params['host'], port=mongo_connection_params['port'], username=mongo_connection_params['username'], password=mongo_connection_params["password"], database_name=mongo_connection_params['db'], collection='logs')

It happens here actually :

if self.username is not None and self.password is not None: auth_db = self.connection[self.authentication_database_name] self.authenticated = auth_db.authenticate(self.username, self.password)

Looks like authenticate method has been removed in the later version of pymongo but log4mongo is still using it.

I resolved it by specifying Mongo URI as host parameter : db_handler = MongoHandler(host=os.environ[EnvVars.MONGO_URI], database_name=mongo_connection_params['db'], collection='logs')
