While attempting to set up a simple test file following the jest documentation, I encountered several linter errors:

connection:
The type 'Promise<MongoClient> & void' is missing properties such as '{ db: (arg0: any) => any; close: () => any; }': db, closets(2739)globalThis.MONGO_URI_:
Element implicitly has an 'any' type because type 'typeof globalThis' lacks an index signature.ts(7017)useNewUrlParser:
No overload matches this call. Overload 1 of 4, '(url: string, callback: Callback<MongoClient>): void', gave the following error. Argument of type '{ useNewUrlParser: boolean; useUnifiedTopology: boolean; }' is not assignable to parameter of type 'Callback<MongoClient>'....I tried setting up a global.d.ts (following these solutions) file with the given declarations below:
export interface globalThis {}
declare module globalThis {
var __MONGO_URI__: string;
var __MONGO_DB_NAME__: string;
}
export interface global {}
declare global {
var __MONGO_URI__: string;
var __MONGO_DB_NAME__: string;
}
Although I initially believed this solved the globalThis.__MONGO_URI__ error, it reappeared after restarting VS Code.
