Mongoose Property 'x' does not exist on type 'Document'

The mongoose.model method accepts a type that defaults to mongoose.Document, which won't have properties you want on your User document.

To fix this, create an interface that describes your schema and extends mongoose.Document:

export interface UserDoc extends mongoose.Document {  email: {    type: string;    unique: boolean;    required: boolean;  }  ...}

Then, pass that through as the type for your model:

export = mongoose.model<UserDoc>('User', userSchema);

When I defined my entity interface I had it extending "Document" but had not imported anything.

When I crtl+click on it though I can see that it incorrectly thinks I was referring to the built-in node object "Document":

/** Any web page loaded in the browser and serves as an entry point into the web page's content, which is the DOM tree. */interface Document extends Node, DocumentAndElementEventHandlers, DocumentOrShadowRoot, GlobalEventHandlers, NonElementParentNode, ParentNode, XPathEvaluatorBase {

After I explicitly told it to use Document from the mongoose library things worked. 👍

import { Document } from 'mongoose';
