Does this happen on your instance or only on the demo? The demo is cleaned up periodically which may cause these kinds of errors.

If it happens on your instance, what do you see in the logs?

Happens exactly like that on my instance, errors in the browser console are the same.

Docker logs show this when i click "Request a copy of my Vakunja Data" (Nothing happens in the UI).

@joren485 commented on GitHub (Feb 13, 2026):

I encounter the same problem, using the vikunja/vikunja:latest Docker image in a docker compose setup. I get the same error message: error creating temp file: open /tmp/vikunja-export-3581461698.zip: no such file or directory

This might be happening because the Docker image is based on scratch, which does not have a /tmp/ folder.

I can reproduce it using the standard docker-compose.yml file:

---

  vikunja:

    environment:
      VIKUNJA_SERVICE_PUBLICURL: "http://127.0.0.1/"

I worked around this by adding a tmp directory mount to my compose.yaml:

[...]
    volumes:
      - ./files:/app/vikunja/files
      - ./config.yml:/etc/vikunja/config.yml
      - ./tmp:/tmp:rw
[...]

I had to

chown 1000 tmp/

to make it writable by the vikunja docker container.

Does this work with the latest unstable build? There have been a few fixes lately around file permissions that might have fixed this.

Did you request an export before trying to download it?

There was another bug in the frontend that showed the button to download it when none was available.

Hi

I solved the problem with a tmpfs directive in my docker-compose.yml

volumes:
     - type: tmpfs
       target: /tmp

No need to create a tmp folder, no need to chown or chmod.
