Hi Harry,
I wonder if you know how to change the content-type of Kong’s error responses for example :
HTTP/1.1 404 Not Found
Date: Fri, 10 Jul 2020 15:48:27 GMT
Content-Type: application/json; charset=utf-8
Content-Length: 48
X-Kong-Response-Latency: 0
Server: kong/2.0.4
Set-Cookie: 0eaf34af1edaad4faae9675c335b76bf=30c0dd94e9d5a54e8a040ff5fcac1456; path=/; HttpOnly
{“message”:“no Route matched with those values”}
