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

Using the errors.wrap property introduced in 17 I'm getting rid of the quotes, and it's working on everything I've seen so far, except when using the with rule. It puts the quotes back in. In the below code, if you change a value to 1, then it will throw the correct error formatting around the label of a, but if a is the correct format (i.e. string), then the with error will throw, showing the quote marks.

const test = Joi.object({
   a: Joi.string(),
}).with('a', 'b');

const { error } = test.validate({ a: 'test' }, { errors: { wrap: { label: '*' } } });
console.log(error.details[0].message);
// "a" missing required peer "b"

What was the result you got?

"a" missing required peer "b"

What result did you expect?

*a* missing required peer *b*
