Tell us what’s happening:
My Repl.lt appears to be giving the right output for the json gateway
but when I try to submit my solution link; it still says The response of the endpoint
“/json” should change according to the environment variable
MESSAGE_STYLE. When I test it in the browser ; the response is

message	"HELLO JSON"
