Error 400 when switching Solid App on the same domain (but different paths)

Build a Solid App Solid App Development FAQs

I have two (actually several) Solid Apps deployed on the same domain but different paths. This is a result of deploying multiple github pages under my account.

After using one App, I visited another one. Then, I was automatically directed to some errors on my Pod’s site (instead of the App’s):

Error reading file: Error: Web error: 400 (Bad Request) on GET of <https://SOLID-SERVER/.oidc/auth?client_id=HIDDEN&redirect_uri=https%3A%2F%2Fme.ryey.icu%2Fknoodle%3Fstate%3D15f244ce57274c918d56d977c8f4cbd7&response_type=code&scope=openid+offline_access+webid&code_challenge=HIDDEN&code_challenge_method=S256&prompt=none&response_mode=query>

(some parts replaced with HIDDEN in case sensitive.)

I found this post in the forum, which says this is caused by restorePreviousSession used together with different redirect URLs. This sounds like the problem for me.

So, my question is: how can I get out from this situation, from the user side?
I cannot log-out at the moment, so cannot clear the session (unless using browser Dev Tools).

Unfortunately authentication is bound to the domain, so if you host apps on the same domain, you’ll run into issues like this. I’m not aware of a way around that other than using different domains.

There is currently a feature request for this on solid-client-authn: Host several applications under the same origin · Issue #1647 · inrupt/solid-client-authn-js · GitHub. However, there are a lot of assumptions made for things coming from the same domain, so I’m not sure it how possible it is to properly handle authentication to separate clients if they share a same origin.
