Siri Shortcut: Log my Weight

I found “Log My Weight” in the Siri Shortcuts (which I think came with Siri Shortcuts) and decided to give it a try today. It works when interacting with it on my iPhone, but imagine my surprise when I tried to invoke it via Siri, I got this error message.

I don’t have an Apple Watch, nor was I aware that Siri Shortcuts require an Apple Watch. Naive that I am, I would have thought Apple would ship sample workflows that actually work on the iPhone.
What am I doing wrong?

Did you set it up as Siri Shortcut? Only having it as Shortcut don’t work.

Duh - that was the missing step! Thanks a bunch…
