Custom error handler

[kraiovsky]

Hi,

let's say I throw an error in the route handler:

const handler = () => async (ctx, next) => {
  try {
    // do something
    await next()
  } catch (err) {
    ctx.throw(500, err)
  }
}

and handle the error with a global middleware:

const errorHandler = () => async (ctx, next) => {
  try {
    await next()
  } catch (err) {
    ctx.status = err.status
    ctx.message = 'error message'
    ctx.body = 'error body'
  }
}

Pino would not log original ctx.throw and log INFO request complete with req and res objects, but no error itself.

Q:

1. how do I add error to this event?
2. alternatively, if I log the error myself with ctx.logger.error, how to enrich it with other meta data i.e. timestamp, context etc.?

thank you!

UPDATE to (2)
Apparently, if logged ctx.logger.error({ err }) it would add req and more meta and context around an error.
Was it documented somewhere that I missed and is worth documenting?

Would it be the "proper" way to log errors in custom error handler?

@kraiovsky Did you find any workaround to this?
