Property 'Email' does not exist on type 'typeof Types'

[Juhil Somaiya]

I was creating a custom schema type with mongoose and typescript with express as backend but I'm getting the following error
::  Property 'Email' does not exist on type 'typeof Types'


Here's my code to create a custom schema

import mongoose from 'mongoose';

class Email extends mongoose.SchemaType {

    constructor(key, options) {

        super(key, options, 'Email');

    }

    cast(val) {

        if (typeof val === 'string' && !val.match(/^.+@.+$/)) {

            throw new Error('Email is invalid');

        }

        return val;

    }

}

// Don't forget to add `Email` to the type registry

mongoose.Schema.Types.Email = Email;

Is there anything I'm missing here or is it like that we need to give reference to this file?
