The content type "application/json" is not encoded by catalyst, because
most of the serializers prefer to output bytes not characters (with the,
good or wrong, reason that json is data, not text). There you are
storing a decoded string, declaring the content type, and serve the
body. Which of course is not going to work.

https://metacpan.org/pod/Catalyst#ENCODING

It says: If you are producing JSON response in an unconventional manner
(such as via a template or manual strings) you should perform the UTF8
encoding manually as well such as to conform to the JSON specification.

And setting the json manually *is* an unconventional manner.

I hope this helps.

Best wishes
