Issue running “Good Night” scene from HomePod mini

Ever since a few days ago, whenever I say “Siri, good night” she always replies “Sorry, something went wrong.” However, she has no issues with “Siri, good morning,” or any other command. Moreover, Siri has no issues with the good night scene when invoked from my iPhone. Even more strangely, I can circumvent the issue by saying “Siri, run the good night scene,” and she does it without a problem. What’s going wrong here and how can I fix this? I’m on the latest OS on all devices and have a strong network connection.

I tried deleting and remaking the good night scene. I’ve also tried resetting the HomePod. All to no avail!
