  • node version: 6.9.1
  • joi version: 10.0.1 - extension 1.0.0
  • environment (node, browser): node
  • used with (hapi, standalone, ...): standalone
  • any other relevant information:

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

Fields with format option become required even if they are written as optional

const BaseJoi = require('joi')
const Extension = require('joi-date-extensions')
const Joi = BaseJoi.extend(Extension)

const schema = Joi.object().required().keys({

const data = { }

Joi.validate(data, schema, { allowUnknown: true }, (err, validatedData) => {
    if (err) {
        console.log('Validation error : ', err)
    } else {
        console.log('Validation success')

Which result you had ?

'"date" must be a string with one of the following formats YYYY-MM-DD'

What did you expect ?

Data should be a valid result
