How do I connect TypeORM to MongoDB? I receive errors while trying to connect - mongodb

Question

I have a NestJS and TypeORM project going. I am trying to connect it to my MongoDB database.
Here is the list of my MongoDB projects from the https://cloud.mongodb.com/ website:
The only name I can see for these is "cluster0" like here:
And then in my .env file I have:
MONGODB_CONNECTION_STRING=mongodb+srv://roland:<myActualPassword>#cluster0.7llne.mongodb.net/?retryWrites=true&w=majority
MONGODB_DATABASE=cluster0
and then the entrypoint to the application:
import { Module } from "#nestjs/common";
import { SchedulingController } from "./scheduling.controller";
import { SchedulingService } from "./scheduling.service";
import { ConfigModule } from "#nestjs/config";
import { TypeOrmModule } from "#nestjs/typeorm";
import { Meeting } from "./db/Meeting.entity";
#Module({
imports: [
ConfigModule.forRoot(),
TypeOrmModule.forRoot({
type: "mongodb",
url: process.env.MONGODB_CONNECTION_STRING,
database: process.env.MONGODB_DATABASE,
entities: [__dirname + "/**/*.entity{.ts,.js}"],
ssl: true,
useUnifiedTopology: true,
useNewUrlParser: true,
}),
TypeOrmModule.forFeature([Meeting]),
],
controllers: [SchedulingController],
providers: [SchedulingService],
})
export class SchedulingModule {}
But I see these errors:

edit: I'm fairly certain my MONGODB_CONNECTION_STRING and MONGODB_DATABASE are set properly, anyone know what else could be causing these errors?

Answer 1

Try to set useUnifiedTopology=false.
