unable to connect to mongodb using deno inside container

First of all, I want to mention that when I run deno task preview on my local machine / laptop, it works 🎉 . No issues there. But I need to run my deno program inside a container for depolyment reasons (currently using fly.io) it fails. I'm using the official mongodb npm client. I use it via an import map (maybe that matters?), deno.json:

{
  "imports": {
    "db": "npm:mongodb@6.3.0",
  }
}

{
  "imports": {
    "db": "npm:mongodb@6.3.0",
  }
}

import { MongoClient } from "db";
// ...
const mongoClient = new MongoClient(url);
await mongoClient.connect();
// ...

import { MongoClient } from "db";
// ...
const mongoClient = new MongoClient(url);
await mongoClient.connect();
// ...

And when I try to run the code in a container I get the following error:

Task preview deno run -A main.ts

checklist: - same version of deno both places - I've tried connecting to mongodb with the deno package mongo but I get another error about the driver not supporting load balancing... so I guess it's just out of date? (6 months since last release) - I've tried to base my image on ubuntu:latest (install deno + run) same issue 🤔
