When using res.json(Number) you get server error about express-mung

[richardschneider]

Good catch. The current version of res.send does not allow a Number. Older versions did allow setting of status code. In either case, returning a Number with mung will fail.

I'm thinking the code should be changed to

return res.send(String(json));

Would this work for you?

This will probably work however the response content-type will be text/plain instead of application/json.
It is possible to assume that if I use res.json, even though the value is not array or object, we will use res.json instead of res.send?
