You can also try this way, I have been using it for long time and working fine for me.

If your array is array of objects than use below:

const Joi = require('joi');

let schema = Joi.object().keys({
            items: Joi.array().items(
                Joi.object({
                    item_id: Joi.number().required(),
                    item_qty: Joi.number().required(),
                    item_type_id: Joi.number().required(),
                    item_qty: Joi.number().required(),
                    base_price: Joi.number().required(),
                    actual_price: Joi.number().required(),
                })
            ).required(),
        });

        let errors = Joi.validate(req.body, schema);

if you array is simple array than:

let schema = Joi.object().keys({
                items: Joi.array().items(
                Joi.number().required()
            ).min(10).required(),
            });
