This is my docker compose:

services:
  deno:
    image: denoland/deno
    working_dir: /server
    restart: always
    command:
      - deno
      - --check
      - --watch
      - --allow-all
      - --inspect=0.0.0.0:9229
      - index.tsx
    ports:
      - 127.0.0.1:8000:8000
      - 127.0.0.1:9229:9229
    volumes:
      - ./server:/server
    depends_on:
      - db

Oddly enough after trying around a few more times it now works. And now I can't reproduce the crash anymore. 🤔
