Description

Version: v1.0.0-rc4
Platform: Docker
OpenID: Authentik

I see issues in the UI where it returns Not Found 404 (this is new in RC4, I didn't see this behaviour in RC3).

  1. I open vikunja home at https://<vikunja.domain>
  2. click to open an issue
  3. refresh page and it returns JSON {"message":"Not Found"}

To fix, I have to delete the /tasks/<id> from the address bar and reload the page. I can't reproduce this on the demo site, so I must have a config issue and I'm not entirely sure where to look.

I did a compose down/up followed by the above steps, below are the full logs leading up to the 404:

I'm not sure if this is related, but I also notice errors with the gethomepage Vikunja widget:

And these are the vikunja logs for the gethomepage widget info fetch

I can confirm the same issue as described above. Everything worked in RC3, this is a new issue in RC4.

On top of the 404 issue with Tasks, I also get this issue with Projects. The same workflow, just open a Project, and then F5 / refresh for it to break:

Same happens with Tasks as described in the above post.

Not sure if this is relevant, but I experience the same issue and I'm not using external IdP

Just tested on the latest docker image and the bug has been successfully fixed. Sorry for the noise
