How can we help?

I am trying to understand how to make custom errors in custom validators, and what properties I can control with it. But I can't seem to figure out the syntax of it.

This one

helpers.message({ message: 'hello world', code: 'any.custom', details: 'hi' });

gives me:

Error code "custom" is not defined, your custom type is missing the correct messages definition].

This one results in

helpers.error('string.UUID', { key: 'properties', value: 'what' });

Error code "string.UUID" is not defined, your custom type is missing the correct messages definition]

The example from docs like:

helpers.error('string.UUID')

Works, but I don't control anything here.

Is there a way to control data that will be in the details property on ValidationError, or am I missing something? Docs are lacking the more complex example about this, and I am kind of lost here.

const bookSchema = Joi.object({ title: Joi.string().required().error((error)=>{ return { message:'title is must' } }).label('title'), author: Joi.string().required(), });

Getting error after executing this code :
Error :
Error: error() must return an Error object

Thanks

@TheFedaikin helpers.message({ custom: 'hello world' }); should work
