When loading a deep url while not being logged in (anymore) website hangs, rather than showing 404

[corneliusroemer]

Using official Plausible Cloud hosting or self-hosting?

Plausible Cloud from plausible.io

Describe the bug

When I load a deep URL to my website's dashboard, e.g. https://plausible.io/foo.org (if my website was foo.org) and I haven't been on plausible in a while (refreshing my auth token), the website get stuck in some "pretending to load" state forever, rather than showing a 404 or redirecting to login page.

This is resolved by reloading the page, upon which I'm shown the correct 404 with button to login.

Expected behavior

When I load a deep URL, I either get to see the page, or I get shown 404, but the website shouldn't get stuck showing a "loading" page forever

Steps to reproduce

Might be a bit tricky to reproduce as one needs to wait for a token to expire. But this is essentially what I do:

1. Log in to plausible
2. Load my dashboard url, e.g. https://plausible.io/foo.org
3. Not use plausible for a long time, not sure what the minimum required is to show the bug, it might be as much as a month or more, I rarely check plausible. The time could also be shorter. Hard to tell for me.
4. Load the dashboard url again https://plausible.io/foo.org
5. Observe result: a loading page (unfortunately I forgot to screenshot when it happened and due to the difficulty in reproduction I might not be able to for a while)
6. Reload page
7. Observe correct result: 404
