.min(2)

.required()
.messages({
'string.base': `"a" should be a type of 'text'`,
'string.empty': `"a" cannot be an empty field`,
'string.min': `"a" should have a minimum length of {#limit}`,
'any.required': `"a" is a required field`
})

const validationResult = joiSchema.validate({ a: 2 }, { abortEarly: false });
console.log(validationResult.error); // expecting ValidationError: "a" should be a type of 'text'
