Connecting to Deno MongoDb in Docker throws uncaught promise (in wsl2)

Question

The project runs in Deno.
I'm trying to connect the MongoClient in Deno to a MongoDb container running in Docker.
The docker container is running in wsl2 with the wsl ip 172.18.96.38 and exposing port 27017.

Connecting to it with the following code leads to an error:

import { MongoClient } from "https://deno.land/x/[email protected]/mod.ts";

const uri = 'mongodb://admin:[email protected]:27017'
this.mClient = new MongoClient();
await this.mClient.connect(uri);

error: Uncaught (in promise) Error: MongoError: "Connection failed: MongoError: {\"ok\":0,\"errmsg\":\"no such command: 'hello'\",\"code\":59,\"codeName\":\"CommandNotFound\"}"
      throw new MongoError(`Connection failed: ${e.message || e}`);
            ^
    at MongoClient.connect (https://deno.land/x/[email protected]/src/client.ts:26:13)
    at async Function.initMongoClient (file:///home/robert/repos/myDenoWebsite/backend/src/utils/mongoClientWrapper.ts:54:9)

According to the errmsg the error is 'no such command: 'hello'. What does this mean?

This is my docker-compose.yml for mongo btw:

version: '3.8'

services:
  mongodb:
    image: mongo:4.4-bionic
    container_name: my-mongodb
    ports:
      - 27017:27017
    environment:
      - MONGO_INITDB_ROOT_USERNAME=admin
      - MONGO_INITDB_ROOT_PASSWORD=admin
    volumes:
      - mongodb:/data/db
      - mongoconfig:/data/configdb

volumes:
  mongodb:
  mongoconfig:

I got a same error, so I found an alternative way

This is my solution

import { MongoClient } from "https://deno.land/x/[email protected]/mod.ts";

const conn = async () => {
  const client = new MongoClient();
  const srv = `mongodb+srv://admin:[email protected]:27017/<Your Database>?authMechanism=SCRAM-SHA-1&retryWrites=true&w=majority`
  await client.connect(srv);
  return client;
}

export const getData = async () => {
  const conn = await conn()
