Troubleshooting Grafana Rendering Issues in Docker Environment

Hi,
I am running grafana and grafana renderer in 2 docker containers sharing the same network.
When using alerts with rendering I almost always get these 2 same errors (almost always because sometimes it actually works).
These are the errors I can find in the grafana container log:

ERR Browser console error | column=5948 line=178 msg=Moment Timezone found Etc/Unknown from the Intl api, but did not have that data loaded. url=http://grafana:3000/public/build/5950.30ec6aaa9dcece6c3b3c.js
ERR Request failed | stack=Error: Request aborted

Can someone perhaps explain what the problem is, also where can I fine more info on troubleshooting and analyzing these errors myself?

This is my docker compose:

version: '3'

services:
  grafana:
    image: grafana/grafana-oss:latest
    container_name: grafana
    ports:
      - "3000:3000"
    volumes:
      - grafana-storage:/var/lib/grafana
    restart: unless-stopped
    environment:
      - "GF_PANELS_DISABLE_SANITIZE_HTML=true"
      - "GF_SMTP_ENABLED=true"
      - "GF_SMTP_HOST=smtp.gmail.com:587"
      - "GF_SMTP_USER=xxx@gmail.com"
      - "GF_SMTP_PASSWORD=xxx"
      - "GF_SMTP_FROM_ADDRESS=xxx@gmail.com"
      - "GF_SMTP_FROM_NAME=Grafana"
      - "GF_RENDERING_SERVER_URL=http://grafana-renderer:8081/render"
      - "GF_RENDERING_CALLBACK_URL=http://grafana:3000/"
      - "GF_LOG_FILTERS=rendering:debug"
      - "GF_UNIFIED_ALERTING_SCREENSHOTS_CAPTURE=true"
    networks:
      - immich_default
    depends_on:
      - grafana-renderer

  grafana-renderer:
    image: grafana/grafana-image-renderer:latest
    container_name: grafana-renderer
    ports:
      - "8081:8081"
    networks:
      - immich_default

volumes:
  grafana-storage:
    name: grafana-storage

networks:
  immich_default:
    external: true

Thanks
