Error when uploading Attachment

[daniel48411]

Hello, have resently started to use Planka (planka:2.0.0-rc.3) an I really like it but I am not abel to upload attatchments to the cards. When choose attatchment -> From Computer and when adding it the card window flashes and nothing happens. In the console I get three errors:

• 500 (Internal Server Error)
• SyntaxError: Unexpected token 'I', "Internal S"... is not valid JSON
• The above error occurred in task queueRequest

Have anyone else this problem or have I set up Planka incorrectly? I am running it on a Windows 11 pc using docker and Rancher desktop.

First edit:
I have found the following in the log:
planka-1 | 2025-06-13 08:28:12 [E] Sending 500 ("Server Error") response:
planka-1 | EACCES: permission denied, mkdir '/app/private/attachments/1531857904473212524'

ChatGPT says It is beacause I made the the volumes like this: ./attachments:/app/private/attachments
Is that the problem? If so how do I set up the compose file to get the folders to be in the same folder as the compose file? I make a backup of that folder.

Second edit:
Well it seems I must have made a error somewhere, I have made a new container without changing anything from the original compose.yml file and now it works.

Greetings, Daniel

Hey! I think the issue might be related to write permissions on the mounted folder. You can try running chown 1000:1000 ./attachments on the host and then try uploading again.

Hello, thanks for answer.
I got it to work the last thing I did yesterday. I did it by running these commands:

• wsl -d ranger-desktop
• sudo chmod -R 777 /mnt/c/docker/planka/attachments
• sudo chmod -R 777 /mnt/c/docker/planka/background-images
• sudo chmod -R 777 /mnt/c/docker/planka/db-data
• sudo chmod -R 777 /mnt/c/docker/planka/favicons
• sudo chmod -R 777 /mnt/c/docker/planka/user-avatar

These may open access too much, so they might not be a great way to solve it but it works.

Also Rancher Desktop decided upgrade and in version 1.9 they have restricted access to wsl -d ranger-desktop so it seems I am not able to change it again at least not that way
