I have tried the following code:

put '/upload/:file' =>  sub {
     my $upload_dir = "c:/Fotis/INA-CERTH/Microme/PathTrace/WebApp/PathTraceWS/UPLOADS";
     my $filename = params->{file};
     my $uploadedFile = request->upload($filename);
     $uploadedFile->copy_to('$upload_dir');

     debug "My Log 1: " . params->{file};
     debug "My Log 2: " . ref($uploadedFile);

     return "DONE";
};

However, the problem is probably the same as before:
/
//request to PUT /upload/test crashed: Can't call method "copy_to" on an undefined value/

What I really cannot understand is why the second debug line returns empty (...ref($uploadedFile)...).

Well that's embarrassing... However, I corrected it and the problem remains (for some reason, it doesn't get the file).

Thank you very much for your time!

Regards,

Fotis
