Question

Hi everyone Does anyone know if there s a way to access a deployment name in an on flow failure hook I understand that `flow flow run state` are the 3 parameters passed to the hook but it s not clear to me how to access the deployment name from any of these Would be greatly appreciated as we have some flows deployed many times with different parameters and would be very useful for understanding what is failing at a glance in our Slack alerts Thanks

Hey you should be able to do something like this ```from prefect import flow from prefect runtime import deployment def on failure hook flow flow run state print f THIS IS FAILED IN DEPLOYMENT deployment name flow on failure= on failure hook def my flow raise ValueError I m a bad flow if name == main my flow ```

when executed from a deployment you ll get something like ```Traceback most recent call last File Users jakekaplan opt anaconda3 envs demo flows lib python3 10 site packages prefect engine py line 833 in orchestrate flow run result = await flow call aresult File Users jakekaplan opt anaconda3 envs demo flows lib python3 10 site packages prefect internal concurrency calls py line 292 in aresult return await asyncio wrap future self future File Users jakekaplan opt anaconda3 envs demo flows lib python3 10 site packages prefect internal concurrency calls py line 316 in run sync result = self fn self args self kwargs File Users jakekaplan PycharmProjects demo flows on failure py line 9 in my flow raise ValueError I m a bad flow ValueError I m a bad flow 10 34 44 517 | INFO | Flow run meek tarsier Running hook on failure hook in response to entering state Failed 10 34 44 873 | INFO | Flow run meek tarsier Hook on failure hook finished running successfully 10 34 44 875 | ERROR | Flow run meek tarsier Finished in state Failed Flow run encountered an exception ValueError I m a bad flow THIS IS FAILED IN DEPLOYMENT on failure deployment 10 34 45 614 | INFO | prefect flow runs worker Process 93245 exited cleanly ```

This is great thank you I had been messing around with `prefect runtime deployment` locally but didn t want to go through the steps to test it in a deployed flow
