[BUG] Impossible to share (self hosted DrawDB)

[lagraviereScience]

Hi all,

Thanks for this amazing project <3

Identical issue

This issue here https://github.com/drawdb-io/drawdb/issues/584 reports the same problem The person who created the issue seems to have solved their problem, but forgot to share how they did it.

Here's the issue

When I click the share button (top right of the screen), I get this error:

172.18.0.4 - - [18/Oct/2025:19:37:59 +0000] "POST /undefined/gists HTTP/1.1" 405 157 "https://drawdb.blabla.blabla/editor" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:144.0) Gecko/20100101 Firefox/144.0" "172.18.0.1"

Technical Setup

I'm running DrawDB with docker compose (in portainer). As far as I can tell, everything is running fine except that "share feature":

  drawdb:
    image: drawdb
    networks:
      - private_secured_network
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.drawdb.rule=Host(`blabla.blabla.blabla`)"
      - "traefik.http.routers.drawdb.entrypoints=websecure"
      - "traefik.http.routers.drawdb.tls.certresolver=myresolver"
      - "traefik.http.services.drawdb.loadbalancer.server.port=80"
    environment:
      - VITE_BACKEND_URL=https://drawdb-api.blabla.blabla
  drawdb-server:
    image: node:20-alpine
    environment: 
      - CLIENT_URLS=https://drawdb.blabla.blabla
      - MAIL_PASSWORD=
      - MAIL_USERNAME=
      - MAIL_SERVICE=gmail
      - PORT=5000
      - NODE_ENV=prod
      - GITHUB_TOKEN=a-gh-token
    container_name: drawdb-server
    working_dir: /var/www/html
    volumes:
      - /home/blabla/Desktop/apps/drawdb/drawdb-server:/var/www/html
    command: sh -c "npm install && npm run dev"
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.drawdb-api.rule=Host(`drawdb-api.blabla.blabla`)"
      - "traefik.http.routers.drawdb-api.entrypoints=websecure"
      - "traefik.http.routers.drawdb-api.tls.certresolver=myresolver"
      - "traefik.http.services.drawdb-api.loadbalancer.server.port=5000"
    networks:
      - private_secured_network
    
networks:
  private_secured_network:
    external: true

I'm guessing that, after looking at the code, maybe the issue is with this parameter? VITE_BACKEND_URL=https://drawdb-api.blabla.blabla?

Did I miss anything?

In the first message, there's the error message I get, I put here again:

172.18.0.4 - - [18/Oct/2025:19:37:59 +0000] "POST /undefined/gists HTTP/1.1" 405 157 "https://drawdb.blabla.blabla/editor" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:144.0) Gecko/20100101 Firefox/144.0" "172.18.0.1"

Also, it seems that this feature is not even functioning on the official DrawDB website :')

aws is down :')

regarding the self hosting issue make sure the VITE_BACKEND_URL env gets set correctly

Thanks for your reply

Yep yep, VITE_BACKEND_URL is set correctly 🤷

Side note and just to be sure about this feature: the share button, seems to generate a script of the current drawing and uses Github Gist to share it, did I get this correctly?

[1ilit]

try passing the VITE_BACKEND_URL as an ARG

yep, sharing creates gists
