node-express error : express deprecated res.send(status): Use res.sendStatus(status) instead

Question

I am trying to send an integer via response.send() but I keep getting this error

express deprecated res.send(status): Use res.sendStatus

Answer 1

(as mentioned in the comments already)

The manual states:

The body parameter can be a Buffer object, a String, an object, or an Array.

So integers aren't directly supported and need to be converted to one of those types first. For instance:

response.send(String(idTest));
