404 Error when using entityID URI in Actionable Notification

I’m working on my first actionable notification in the Companion app. I’m on version beta-10230-b7c6be45-full. If I add the action example shown in the documentation:

- action: "URI"
  title: "View the sun"
  uri: "entityId:sun.sun"

The notification appears but I get a 404 Error from the companion app when clicking the link. Here’s the relevant lines from the companion app log.

Not sure what I could be doing wrong.

Are you sure you entered the yaml correctly case sensitive?

I see what you did there. :stuck_out_tongue_winking_eye: Let me try that again!
