You can use when condition. I am giving one example here but can be done for other fields as well.

const withdrawDepositValidatorSchema = Joi.object({
  type: Joi.string(),
  name: Joi.when(Joi.ref("type"), {
    "is": Joi.string().valid("Withdraw"),
    "then": Joi.string(),
    "otherwise": Joi.forbidden()
  }),

i updated the question , i forgot to add amount , bonus , userId to first set, [amount,bonus,userId] is common to both.

I have provided you the way to do it. If it is done for one field, I am sure you can workout for the other fields as well
