The issue you're facing with the URL in Slack notifications seems to be a common problem with URL configurations in self-hosted Prefect setups. Your Slack notification is showing

localhost

instead of your specified

prefect_api_url

. ### Solutions and Workarounds: 1. Configure Base URL with Environment Variables: Ensure that your Prefect deployment configuration has the correct base URL settings. The URL should be set in the environment variables or the configuration file under

PREFECT_API_URL

.

yaml
   environment:
     - PREFECT_API_URL: <http://prefect-ui.stg.ludeo.com/api>

2. Update Prefect UI Configuration: Verify that your Prefect UI configuration is also set correctly, as it might be defaulting to

localhost

. 3. Check Prefect Settings: Review the notification settings you have configured on the Notification page within Prefect: - Navigate to the Notifications page - Edit the notification to ensure it isn’t hardcoded with

localhost

4. Custom Notification: Consider customizing your notification messages. Add a way to dynamically construct the URL based on the environment you are working in. This would involve creating a custom Slack notification template that reads from a configuration file or environment variables. Example:

python
   import os

   prefect_api_url = os.getenv('PREFECT_API_URL', '<http://default-url.com>')
   flow_run_url = f"{prefect_api_url}/flow-runs/flow-run/{flow_run_id}"

For further details, you can also refer to the Prefect documentation on how to set up and customize notifications: https://docs.prefect.io/latest/guides/host/ Additionally, there are associated GitHub issues that might be relevant: - GitHub issue on page refresh and wrong resource address: (https://github.com/PrefectHQ/prefect/issues/10807) - GitHub issue on customizing notification messages: (https://github.com/PrefectHQ/prefect/issues/9291) I hope this helps solve the problem with your Slack notification URLs.
