What are you trying to achieve or the steps to reproduce?

I was trying to use the errors property in the ValidationResult object but it is always undefined, after reading the related docs I saw that the validation errors are returned in the error property, but errors is included in the ValidationResult type, see: https://github.com/sideway/joi/blob/c451ef5575c40622ea6bd64810a79ea10e5cb020/lib/index.d.ts#L644-L649.

// `error` is `ValidationError` if validation errors are found
// `errors` is always `undefined`
const { error, errors } = uploadParamsSchema.validate(params)

What was the result you got?

errors is always undefined

What result did you expect?

errors behaves as error or errors is not included in the ValidationResult type
