Response headers from error should be application/json

The response of the error given by express-validation is text/html; charset=utf-8 when it should be application/json; charset=utf-8. Because it is text/html responses given back are parsed as below:

{"status":400,"statusText":"Bad Request","errors":[{"field":"content-type","location":"headers","messages":["\"content-type\" must be one of [application/json;charset=UTF-8]"],"types":["any.allowOnly"]}]}

Order of middleware is relevant, express-middleware basically calls a next(err) with err being the JSON error.

So the next middleware receives this object, if there is not a next middleware in the chain of /users then it refers to the “global” chain, but it has to be defined after it.

It is a tricky implementation for newcomers, but it’s not an express design, it is based off Ruby on Rails (afaik)

PS: just google “middleware pattern” and have a nice read :neckbeard:

Yup, just tested it and that is what the issue is. Is there a reason why the order of such a thing would cause this to happen in express? Sorry, I’m extremely new to backend JS.
