I get the following error message when creating a Metric alert in Sentry: Each trigger must have an associated action for this alert to fire.

The message appears when you try to create an alert with two trigger thresholds: Critical and Warning, and only one of those has an action in Step 4 "Set actions."

To solve the issue, add a new action for the missing trigger. You should have at least one action for Critical Status and Warning Status.

More information on how to configure Metric Alerts is available in our documentation.
