Select/Show Tracks in Folder throwing errors

Title

Select/Show Tracks in Folder throwing errors

What do you expect to happen when you run the script/macro?

This has worked for a while and stopped working recently. It is supposed to select/show tracks within a folder. When I run it, I now get the error message:

TypeError: Cannot read property 'titleButton' of null

(Select/Show Tracks in Folder line 8)

Are you seeing an error?

TypeError: Cannot read property 'titleButton' of null (Select/Show Tracks in Folder line 8)

What happens when you run this script?

It seems like whenever I run it I get that error message. I have it as part of several different macros and they all give me the same error message.

How were you running this script?

I used a keyboard shortcut within the target app

How important is this issue to you?
