Hi everyone, I interrupted the

prefect deploy --all

command while it was building the docker image and now it consistently fails to run successfully with this error.

aha! so are you all good now? @Adam Eury

yes, thanks @Nate lol

good to hear, sure thing!

I am running into some other strange issues though. I'm testing the

on_cancellation

behavior and it doesn't always seem to run. In one flow run, I saw this in the logs

Running hook 'handle_cancellation' in response to entering state 'Cancelling'

and then without changing anything at all, I cancelled another run and didn't observe the same behavior.

@Marvin issues about cancellation hooks?

Here are some issues related to cancellation hooks in Prefect: 1. Flow hooks `on_crashed` / `on_cancellation` not executing correctly with KubernetesWorker: This issue reports that the

on_cancelled

or

on_crashed

hooks do not execute when using a Kubernetes worker. The issue was tested in three scenarios: local without a deployment, local with a deployment, and remote with a Kubernetes worker. The hooks worked as expected in the first two scenarios but failed in the third. 2. Prefect `on_cancellation` hook is not called when cancelling a flow during a task submitted to a task runner: This issue reports that the cancellation hook is never called upon flow run cancellation. The user noticed this while trying to add an

on_cancellation

hook to a Prefect flow. 3. No Prefect logger available by default in a vanilla Python function, even a callable on_cancellation hook: This issue reports that the

on_cancellation

hook threw an error and was unable to be called successfully when a flow was canceled mid-task run. I hope this information is helpful. If you need more details, I suggest visiting the links provided.

I'm testing running flows on Kubernetes.

i think the first issue above might be relevant

thanks! taking a look
