in reply to write_file to_json in Dancer app

The error message suggests to me that $filename is empty. Maybe you need to initialize it from a different place in your configuration?

Does uploading work if you hardcode the value for $filename instead of using the configuration?

    aha, yes, thanks. That does work.
    The file is updated if I refresh the browser. Well, with not much I'll have to admit but at least the modification time changes.
    So, I'm not there with the format but I should be able to work that out.
    Thanks!

      updating the code between the comment lines to the code I mention below makes that the data is been written to a 'json' file. Not very clever code yet as the data gets overwritten every time you run the script but that is a separate issue.
          #-------v this does work --------#
    my $filename = "testme.json";
    my $json = -e $filename ? read_file $filename : '{}';
    my $data = from_json $json;

    $data = \@photos;
    write_file $filename, to_json($data);
