This issue is to determine whether the task should fail if the file is not found. I see. In that case, I don't think it makes sense to have the task succeed if a file is not found. A 'success' would not have much meaning anymore besides that the task simply ran. The interpretation of 'success' would become ambiguous i.e. how can you tell if a file was indeed moved or not without having to further dig into the logs? In addition, it doesn't feel very 'airflow-like' since we would be overloading the operator with functionality that already exists through a sensor. I'm not sure what your DAG looks like, but perhaps you can use a `SFTPSensor` and trigger rules for your downstream tasks? There is `soft_fail` for sensors too, if you want the sensor to 'skip' instead of 'fail'. -- This is an automated message from the Apache Git Service.
