There is an error in the documentation

[Allin2000]

And now, let's see that it's alive:

$ curl localhost:3000/api/_ping //error
$ curl localhost:3000/_ping
{"ok":true}
The built in _ping route will tell your load balancer everything is up.

Let's see that all services that are required are up:

$ curl localhost:3000/api/_health //error
$ curl localhost:3000/_health
{"ok":true}
