Did you add a debug print statement inside the loop to see what you are passing to basename() in $file? It really works:

$ perl -MFile::Basename -wE 'say basename("foo.psd",".psd")'
foo

... but passing an undefined value does not:

$ perl -MFile::Basename -wE 'say basename(undef,".psd")'
Use of uninitialized value $_[0] in substitution (s///) at /Users/1nic

fileparse(): need a valid pathname at -e line 1.

The way forward always starts with a minimal test.
