Description

Whenever I try to make an Schema with a property of the Type Boolean Constructor the typescript server sees it as being of the type Date.

error TS2322: Type 'boolean' is not assignable to type 'Date'.

22 course.isPublished = false;
~~~~~~~~~~~~~~~~~~

Found 1 error in src/updatemongo.ts:22

Steps to Reproduce

I just create a TypeScript project with this tsconfig

{
"compilerOptions": {
"target": "ES2015",
"module": "commonjs",
"esModuleInterop": true,
"moduleResolution": "Node",
"forceConsistentCasingInFileNames": true,
"strict": true,
"skipLibCheck": true,
"rootDir": "src",
"outDir": "dist"
}
}

install the latest mongoose available using npm and
try to make an Scheme like this.

import mongoose, { Mongoose } from "mongoose";
const courseSchema = new mongoose.Schema({
name: String,
author: String,
tags: [String],
date: { type: Date, default: Date.now },
prices:Number,
isPublished: Boolean
});

const Course = mongoose.model('Course', courseSchema);

async function updateCourse(id:any) {
const course = await Course.findById(id);
if (!course) return;
course.isPublished = false; //tsc won't compile because it will see it as being of type Date
course.author = 'Another Author';
}

updateCourse("none");

Expected Behavior

Typescript should see it as being of type Boolean
