This is driving me nuts, so I would appreciate any advice. Perhaps it is just a silly oversight on my part. punkish@Lucknow ~/Sites/carbonapp/public/images/models/2bau/years/8$pwd /Users/punkish/Sites/carbonapp/public/images/models/2bau/years/8 punkish@Lucknow ~/Sites/carbonapp/public/images/models/2bau/years/8$ls 2* 2010_nep.gif punkish@Lucknow ~/Sites/carbonapp/public/images/models/2bau/years/8$ So, as you can see, the following file exists /Users/punkish/Sites/carbonapp/public/images/models/2bau/years/8/2010_nep.gif My route is get '/:model_id/year/:year/zoom/:zoom/:output' => sub { my $model_id = params->{model_id}; my $year = params->{year}; my $zoom = params->{zoom}; my $output = params->{output}; # get model_file based on model_id my $dir = config->{'app_dir'} . '/' . config->{'img_dir'} . "/$model_file/years/$zoom"; my $img = $year . '_' . $output . '.gif'; debug("sending '$dir/$img'"); send_file("$dir/$img"); }; My development.log shows [37838] debug @0.008607> [hit #1] sending '/Users/punkish/Sites/carbonapp/public/images/models/2bau/years/8/2010_nep.gif' in /Users/punkish/Sites/carbonapp/lib/carbonapp/models.pm l. 106 and yet, I get the following error in my browser {"error":"No such file: `/Users/punkish/Sites/carbonapp/public/images/models/2bau/years/8/2010_nep.gif'"} Please point me to my stupid ways. -- Puneet Kishor Sent with Sparrow
