Automator's Finder Actions: "Unable to search with Spotlight" I created a workflow like this after asking another question:



It should delete downloads older than 30 days, and has been working fine until today; today I updated to macOS High Sierra.

Now whenever the Application tries to run I'm getting the error




  The action "Filter Finder Items" encountered an error: "Unable to search with Spotlight"


How can I fix my workflow so that it works with this latest version of macOS?
I think I just figured out the problem and it is laughably stupid.

When filtering by extension, you mustn't include the "." in the filter criteria.

So, in your case, filter by IS NOT: "download" instead of ".download"

I love Automator, but sometimes it is hard to follow its logic.
