ERROR "Software error: Can't use an undefined value as a HASH reference at upload.pl line 134."

How can this POSSIBLY be the case when my test proves 100% it's not undefined? This is the line on line 134 and it's saying $file is undefined, right? Well WRONG, the print statement exactly one line above prints the value correctly. Could something else be the problem? 

    print "file = \"$file\"";
    my $type = uploadInfo($file)->{'Content-Type'};
