how to override the default error code of 400 to a more specific 422?

[j-d-carmichael]

• node version - 10 lts
• celebrate version - 10.0.0
• joi version (via npm ls --depth=0 | grep joi) - not important

I am writing a collection of micro services that will work in combination with a few others, not all written in node. I need to align the error status code with the rest of the services, to http status code 422. This package is nice and simple but how can i acheive this, cannot see anything in the readme on changing it from 400.

As some what of a dirty hack, but dictating the status code feels like it should be done in the "errors" middleware:

export default () => {
  return (err, req, res, next) => {
    if (err.joi) {
      res.status(422).json(err)
    } else {
      next(err)
    }
  }
}

@johndcarmichael please check https://github.com/arb/celebrate#errors and https://github.com/arb/celebrate#iscelebrateerr about celebrate errors and the common use for isCelebrate.

Basically, write your own celebrate error handler and check isCelebrate(err) to determine if the error came from a celebrate validation failure.
