Feathering can only be done on a selection so probably the action halts because there is no active selection at that moment.
Not sure what you are saying.
This below shows it found the jpg file.
Is a selection a jpg file?
Maybe this is more complete.

Error: The command "Feather" is not currently available. (-25920)
Now I understand.
I don't know what Feather is but in the action menu in the upper right corner of PS screen I trashed the reference to Feather.
This solved my problem.
Don't know what other problems I may have caused.
Thank you all.
