What are you trying to achieve or the steps to reproduce ?
Describe your issue here, include schemas and inputs you are validating if needed.
I've narrowed it down to this:
'use strict';
const Joi = require('joi');
const schema = Joi.object({
name: Joi.empty()
});
console.log(schema.describe());Which result you had ?
description.flags[flag] = this._flags[flag].describe();

What did you expect ?
schema description.
I also wanted to use lout but it causes same exception when accessing /docs:
Debug: internal, implementation, error
