Hi < Taqi> You can add a hook to every op in your job by doing ``` job hooks= do something on failure def my job ``` see

You might also want to consider using <https docs dagster io apidocs libraries dagster slack dagster slack make slack on run failure sensor|make slack on run failure sensor> Sensors work differently from hooks and require the `dagster daemon` to be running but can catch more types of errors such as if the job fails to start
