Hi,

One thing to note is that only the last engines block will have effect in your config (although that is clearly not the source of this problem).

I was able to reproduce your issue with the test app generated by dancer2 gen -a by adding a line after the template ... statement. My failing file: 

package My::TestApp;
use Dancer2;

our $VERSION = '0.1';

get '/' => sub {
    template 'index' => { 'title' => 'My::TestApp' };
    debug 'after templating';
};

true;

The debug log statement was printed to the log but no output was shown in the browser. Removing/commenting the line fixed the problem. I believe this is because the output of the last line in the handler is what is returned to the browser. (From the doc: "Note that template simply returns the content, so when you use it in a route handler, if execution of the route handler should stop at that point, make sure you use return to ensure your route handler returns the content.") Adding a line with output shows this: 
package My::TestApp;
use Dancer2;

our $VERSION = '0.1';

get '/' => sub {
    template 'index' => { 'title' => 'My::TestApp' };
    debug 'after templating';
    'foo';
};

true;

The browser shows 'foo' with this code.

Do you have any other code in the route handler in sandbox.pm after the template statement?

Hope this helps!

Update: added quote from the doc


The way forward always starts with a minimal test.
