AssertionError [ERR_ASSERTION]: you must pass Joi as an argument

Question

How do I solve this Joi problem(Using express, joi@17.4.2,joi-objectid@2.0.0, ,mongoose) I am trying to link two mongoose schemas using ref as

{
...
   enroledcourses: [{
        type: Schema.Types.ObjectId,
        ref: "courses"
    }]
}

joi validation

...    
enroledcourses: Joi.array().items(Joi.ObjectId()).required()

the course collection is fine i have imported it at index.js as below

const Joi = require("joi")
Joi.objectId = require("joi-objectid")(Joi);

but i end up getting this error enter image description here

AssertionError [ERR_ASSERTION]: you must pass Joi as an argument at joiObjectId (D:\Programing projects\2021\ikodeafrika\ikodeafrikabackend\node_modules\joi-objectid\index.js:6:3) at Object. (D:\Programing projects\2021\ikodeafrika\ikodeafrikabackend\index.js:2:39)

index.js:2:39 being the joi.objectId import above plus i'm getting this when i hover over the joi.objectId import statement

Property 'objectId' may not exist on type 'Root'. Did you mean 'object'?ts(2568) index.d.ts(1998, 9): 'object' is declared here. any

The problem is because joi-objectid@2.0.0 is not compatible with joi@17.4.2.

Fix:
Upgrade joi-objectid to v4.0.2

About the Typescript error (Property 'objectId' may not exist on type 'Root'), you need to augment the type of Joi to add the objectId property. This can be done by creating a declaration file:

// src/types/joi.d.ts
import { Schema } from "joi";

declare module "joi" {
  interface Root {
    objectId(): Schema;
  }
}
