Hi everyone, I have an issue with automations on Prefect3. When I run a prefect server localy and create a slack-incoming-webhook block and an automation that uses the block everything works perfect. However when I create the exact same block and automation on a prefect server that is running on a kubernetes cluster I get the following error when the automation is triggered:

The notification block was invalid: KeyError(\"No class found for dispatch key 'slack-incoming-webhook' in registry for type 'Block'.\

When I run :

prefect block type ls

I see that the block type is registered.

slack-incoming-webhook │ Block holding a Slack webhook for use in tasks and flows │ prefect block create slack-incoming-webhook

Running

prefect block register -m prefect_slack

also didn't solve my issue. Does anyone have a clue what could be the issue? Should I install the prefect_slack integration on the pod of the prefect server?
