Couldn't save to backend database, backend storage cant be accessed

[Anilo1990]

I always get this Error in collab mode. This is my docker-compose which I deploy in Portainer

services:
  frontend:
    image: alswl/excalidraw:v0.17.0-fork-b1
    environment:
      - PORT=8081

networks:
 excalidraw:
  name: excalidraw

When I check the log for StorageBackend there is a warning

WARN [StorageService] STORAGE_URI is undefined, will use non persistant in memory storage

I tried serveral things to integrate the STORAGE_URI into the docker-compose but it's not working. Here someone had the same issue and he has redis in his docker-compose. I tried this but it's not working for me or I did something wrong.

Any idea how I can solve this?

This configurations works, maybe you should check your network policy.

[Anilo1990]

@alswl nope the standard configuration doesn't work for me either :-( I've no special network policy. All other containers are running fine without any issue.

Any idea what I could check further?

Your OS and version. Docker version. Docker compose version.

@alswl DSM 720+ DSM 7.2.1-69057 Update 2

Docker Version (Container Manager) 20.10.23-1437 Docker Compose version 20.10.23, build 876964a

[alswl]

@Anilo1990 try to upgrade to latest docker / docker-compose version.

My version:

Docker version 24.0.6, build ed223bc Docker Compose version v2.23.0-desktop.1

[Anilo1990]

@alswl I think thats not possible. I followed this guide https://www.smarthomebeginner.com/synology-docker-media-server/ but it's not possible to update to 2.23.3 because Synology is using a application called "Container Manager" to run Docker. I executed the command but it still stays on Docker version 20.10.23

[alswl]

Which URL did you open?

If you not run containers in your current desktop, you cannot access the "127.0.0.1" website.

So the VITE_APP_WS_SERVER_URL and VITE_APP_HTTP_STORAGE_BACKEND_URL in your configuration is wrong.

You can check your Web Dev Tools, I think the HTTP request is failed, and even you change the two env by the intranet IP, you will still get error. Because the two url is not HTTPS protocol.

You must register a HTTP SSL cert or sign by you self (with CA cert install).

[Anilo1990]

@alswl I have a signed certificate with Let‘s Encrypt. It looks like this https://excalidraw.mydomain.de

[alswl]

@Anilo1990 you should three domains (frontend / room / storage) or sign one domain but use a Load Balancer(like nginx).

[Anilo1990]

@alswl I can assign subdomains for frontend / room / storage. Can you tell me how I need to modify the docker-compose for that?

[alswl]

modify the docker-compose

It will be a little complicated, user need known the basis of infrastructure management(A.K.A. DevOps).

Maybe I will provide a guide later.

[Anilo1990]

@alswl I thought I only had to add the subdomains somewhere in the docker-compose. I did not know that it is so complicated that I need an extra guide for it

[Anilo1990]

@alswl you had time to write down a guide for my issue so I can solve it?

[kschimpanski]

@Anilo1990 Is the port that you set for the storage service open (8081)? I get the same error in collab mode on a local VM with docker when the port is not open. However the storage log also tells me: WARN [StorageService] STORAGE_URI is undefined, will use non persistant in memory storage

[Anilo1990]

@kschimpanski I have already tried the following:

• enabled port 8081 in my disc station
• Firewall completely deactivated
• Restarted Excalibur services in Portainer after I made a change

The warning message still appears in collab mode.

[Anilo1990]

any idea for a solution @alswl @kschimpanski

[inquam]

You are not using something in front (I use authelia and traefik for instance) that could be setting a CORS-policy that is blocking you?

[Anilo1990]

Nope at that time I wasn't using anything infront of excalidraw.
