Cloudflare Workers + Digital Ocean Managed Postgres DB

Hello, im trying to setup a simple JS POC using Cloudflare workers. tl;dr the worker will query a Postgres DB on Digital Ocean. And i can not make it work at all. I have tried both pg and postgres javascript libraries node_compat is set to true

import { Client } from "pg";

const client = new Client({
  connectionString: "postgresql://u:p@host:p/name",
  ssl: {
    cert: `a redacted cert`,
  },
});

export default {
  async fetch(
    request,
    env,
    ctx
  ) {

    await client.connect();

    const resp = Response.json(/**some response */);
    // Close the database connection, but don't block returning the response
    ctx.waitUntil(client.end());
    return resp;
  },
};

import { Client } from "pg";

const client = new Client({
  connectionString: "postgresql://u:p@host:p/name",
  ssl: {
    cert: `a redacted cert`,
  },
});

export default {
  async fetch(
    request,
    env,
    ctx
  ) {

    await client.connect();

    const resp = Response.json(/**some response */);
    // Close the database connection, but don't block returning the response
    ctx.waitUntil(client.end());
    return resp;
  },
};

Just running client.connect here will make the worker freak out running when making a request to the endpoint. ( Starting the worker with wrangler deploy src/index.js ) Errors out with

 Error
Connection terminated unexpectedly

 Error
Connection terminated unexpectedly

I have tested everything ™️ . Not sure what im doing wrong. Anyone have any insight or guidance?

no_access_to_browser_worker

The Cloudflare docs states that "Workers Browser Rendering API is now in open Beta. During this period, Browser Rendering is available on all plans". But when i try to follow the getting started (https://developers.cloudflare.com/browser-rendering/get-started/screenshots/) i get the following error: workers.api.error.no_access_to_browser_worker Thank you!
