[dancer-users] about send_error message

Hello, For send_error function, for example,  get '/' => sub {   # template 'index';   send_error("Not authorized", 401); }; When running with bin/app.pl directly, the message "Not authorized" can be displayed in the web. But if I run it with starman: plackup -E deployment -s Starman --workers=10 -l 0.0.0.0:3000 -D --access-log=logs/access.log -a bin/app.pl This error message seems lost. Do you know how to fix up it? b/c I wrote the API with dancer, I need to tell the clients what are the errors. Thanks.
