Automator copy file type from one folder to another not working

All this needs to be is a two-action Folder action, where the source folder and destination folder are unique destinations and the destination folder must not be contained within the source folder.

Here is an example using two folders on my Desktop: 1) Foo (source) and 2) WIP (dest). I drop a PDF document onto Foo, and it is copied into WIP. You might want to set the Replacing existinf files on the destination folder if you don't want Finder interrupting your workflow with these:

The Folder Action workflow that I am using:

That workflow was tested on Big Sur 11.6.7. I have an appointment coming up at 1pm EDT, so won't be able to test it on Monterey 12.4 until I return mid-afternoon. At this point, it is a simplistic folder action and I believe it will work unchanged on Monterey too.

I am confused by your description:

> 1) Set the Folder Actions receives files and folders added to "Source Folder"

makes sense - the workflow automatically gets presented with a list of files and folders added to the source folder.

Side issue, not sure why you use 'Files and Folders' if you're just looking for a File, but that may be a separate question.

> 2) Use Get Specified Finder Items action and add the source folder

What? Why? you already have the items passed into your script. Why do you feel the need to Get the source folder again?

Ostensibly, this will override the list of files added to the folder and reset the script to run on a potentially different set of source files.

Ultimately, it isn't entirely clear what your script is trying to do. It would help if you posted a screenshot of your workflow since often subtle details are missed when you try to explain what you think it's doing vs. what it's actually doing.

Also, as Viking hinted, this may be doomed to failure if the destination folder is a subfolder of the source folder. You'll need additional logic added to the script if this is the case.

OK. I created a new folder action on macOS Monterey 12.4, just as it appears in my previous post. A dropped a PDF on the assigned folder and it failed to copy to the designated folder. The Automator gear appears in the menu bar, as it should, but nothing. Have no idea why it would work on Big Sur 11.6.7 and then fail when created new on Monterey 12.4.
