> Hi
> I found a bug in the constructor off the new airflow (1.10.7).
> It's affects me when I am implementing my own operator (I'ts inherit from
> SshOperator)
> The default value for the "self.command" variable is None, while this line of
> code cant run because of the default value:
> {code:java}
> self.get_pty = self.command.startswith('sudo') or get_pty {code}
> My solution right now (In my plugin) is to send value of empty string to the
> constructor:
> {code:java}
> super().__init__(command='', *args, **kwargs){code}
> instead of:
> {code:java}
> super().__init__(*args, **kwargs){code}
> The problematic file is (line 83):
> {code:java}
> /v1-10-stable/airflow/contrib/operators/ssh_operator.py {code}
>
> !ddd.png!
> Thanks
