Report a bug.

What is the current behavior?

The project method is missing from the Aggregate interface.

If the current behavior is a bug, please provide the steps to reproduce.

import { createConnection } from 'mongoose';

const db = createConnection();
const aggregateResults = await db
  .model('SomeModel')
  .aggregate<SomeModelDocument>()
  .project({ // <<-- Not recognized
    someField: true
  });

{
  "compilerOptions": {
    "module": "commonjs",
    "target": "ES2019",
    "rootDir": "./src",
    "outDir": "./lib",
    "declaration": true,
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "lib": ["ES2019"]
  },
  "include": ["src/**/*", "test.ts"],
  "exclude": ["node_modules", "**/*.spec.ts"]
}

What is the expected behavior?

The project method does indeed exists in the aggregate class.

What are the versions of Node.js, Mongoose and MongoDB you are using? Note that "latest" is not a version.

Node	v14.16.0
Mongoose	v5.12.1
MongoDB	v4.0.14	in-memory test

Looks like this got unintentionally removed by a31efa1#diff-7aa4473ede4abd9ec099e87fec67fd57afafaf39e05d493ab4533acc38547eb8. Will be added back in 5.12.2, sorry for the inconvenience! 👍
