I’ve been looking for information on and if there were any changes, but I haven’t been able to find any information. Recently some unit tests we run using started returning:
“code”: “404”,
“message”: “OK”

Our requests to create a mockbin had worked ok until recently. Example request:

curl -v -d ‘{“test”: “ok”}’ -H “Content-Type: application/json” -X POST

I sent some request to a few days ago and it’s work. But recently, i do it again and received response like your question. So i think some problem happen with this site.
Just create your own service and try again with Kong.
