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

Joi 8.0.4 removes meta in the alternative's describe() schema. I'm guessing unintentionally since it's not in the release notes. It also still works for other types.

Repro:

var Joi = require('joi');
var describe = Joi.when('x', {is: Joi.any(), then: Joi.any(), otherwise: Joi.any()}).meta({a: 1}).describe();

console.log(describe.meta);
