Thanks. I took out both debugs. Now I have: 
get '/login' => sub {
    # Display a login page; the original URL they requested is availab
+le as
    # param('requested_path'), so could be put in a hidden field in th
+e form
    # debug "displaying login page";
    template 'login', { path => param('requested_path') };
};

and still no output. I tried the "foo" and didn't see that either. I am getting the error:
[sandbox:22720] core @2025-04-06 16:28:17> Failed to serialize content
+: hash- or arrayref expected (not a simple scalar, use allow_nonref t
+o allow this) at /usr/local/share/perl/5.34.0/Dancer2/Serializer/JSON
+.pm line 40. in (eval 333) l. 1

But I can't tell what's causing it. When I put the debug before the "template" call, the error vanished. Curious. Also, I have seen examples with multiple engines in the config. Can you point me to an example that says only one is allowed? I had 2 in the old working version. Updates: I found that beginning with 1.3091 it is again permitted to have statement after template. I did a debug template ... and the proper "output" is in the log. Now I need to figure out where it's going...
