Joi schema: dynamic allow/items validation - "Method no longer accepts array arguments"

I have the need to "extend"/use the schema.items()/schema.allow() with a array, where items can be added.

const Joi = require("joi");const allow = ["foo", "bar"];const schema = Joi.array().valid(allow);allow.push("baz");const {error, value} = schema.validate(["baz"]);console.log(error || value);

The problem is, items()/allow() do not allow a array as parameter, and using the spread operator does not work.

/home/marc/projects/playground/node_modules/@hapi/hoek/lib/assert.js:21    throw new AssertError(args);    ^Error: Method no longer accepts array arguments: valid    at new module.exports (/home/marc/projects/playground/node_modules/@hapi/hoek/lib/error.js:23:19)    at module.exports (/home/marc/projects/playground/node_modules/@hapi/hoek/lib/assert.js:21:11)    at exports.verifyFlat (/home/marc/projects/playground/node_modules/joi/lib/common.js:214:9)    at internals.Base.valid (/home/marc/projects/playground/node_modules/joi/lib/base.js:297:16)    at Object.<anonymous> (/home/marc/projects/playground/joi-dynamic-items/index.js:6:28)    at Module._compile (node:internal/modules/cjs/loader:1376:14)    at Module._extensions..js (node:internal/modules/cjs/loader:1435:10)    at Module.load (node:internal/modules/cjs/loader:1207:32)    at Module._load (node:internal/modules/cjs/loader:1023:12)    at Function.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:135:12)Node.js v20.11.0

How can i add allowed items to the array that joi picks up the newly added allowed items?
