Hi 👋 I am trying to define my own new Infrastructure class, but getting the error: “No class found for dispatch key ‘xxx’ in registry for type ‘Block’” full info in this thread: https://discourse.prefect.io/t/submission-failed-keyerror-no-class-found-for-dispatch-key-xxx-in-registry-for-type-block/2203/1 Any ideas what am I doing wrong here?

Hi Yaron, did you use

prefect block register

to register your block?

I guess not (-: You are referring to this step?

Yes, that's the one. If the block isn't registered, it won't show up in the UI and your agent also won't be able to find it. You may need to register it separately on the agent machine after you register it with Orion or Perfect Cloud. If the block is in its own package, there's a line you can add to

setup.py

to get your block to auto register when Prefect loads. I'm afk at the moment but can send examples soon if you'd like. To start, I'd suggest looking at

entryoints

in

setup.py

in either the prefect-aws or prefect-azure repositories on GitHub.

Great! I’ll check it and update how it goes

Sounds good! Looking forward to hearing how it goes.

I am also preparing an article how to take it end-2-end. Meaning building a RenderTask infra block

That sounds great! For a while now, I've wanted to write a general article to help users who want to add new infrastructure like this. So I'm very interested in reading about your experience creating the Rendet infra block! 😀

great! I’ll send it once it’s ready

Adding an entrypoint is an excellent suggestion https://github.com/PrefectHQ/prefect/pull/7179 for the next time, please decide whether you post on Discourse or Slack, not both https://discourse.prefect.io/faq

@Ryan Peden So I run this to register the infrastructure block:
