@Marvin I’m using Prefect server 2.14.13. I have two instances of this version on EKS. In one I have a block type of slack-incoming-webhook but in the other I don’t have this block type. What could be the reason?

The discrepancy you're experiencing could be due to the fact that blocks need to be registered before they can be used. Here are a few potential reasons and actions: 1. Block Registration: If a block type is missing on one instance, it might not have been registered. Make sure to register the block if it's not available. You can register a block using Python code or CLI. 2. Custom Block Types: If the Slack incoming webhook block was created as a custom block in one instance, ensure the same custom registration process is followed in the other instance. 3. Prefect Collections: Ensure that the Prefect Slack collection is installed and available in both instances. References: - How to register blocks: Block Concepts - Slack integration guide: Prefect Slack Integration If these steps don't resolve your issue, consider verifying version consistency and checking Prefect server logs for any discrepancies or errors during startup. For detailed registration steps, you might consider using:

python
from prefect.blocks.system import Secret
from prefect_slack import SlackWebhook

# Register the SlackWebhook block type
SlackWebhook.save(name="slack-incoming-webhook")

Then, in your second instance, load it similarly:

python
slack_webhook = SlackWebhook.load("slack-incoming-webhook")

I hope the universe aligns for you once this block is registered.
