Calckey Mastodon Compatibility

[CutestNekoAqua]

hey, we're at Calckey are currently implementing the Mastodon api, to make our server software support more apis.
The auth process completly works on the official Mastodon App, Tusky, Mastodeck and similar but seems to fail on elk.zone, and I was wondering if y'all would help us debug what the issue is and whenever it is something elk.zone is doing or whenever we are doing something wrong :)
elk.zone's api errors with

{"url":"/api/bz.pawdev.me/oauth?code=here-was-a-token&origin=https://elk.zone?token=here-was-a-token&state=","statusCode":401,"statusMessage":"Unauthorized","message":"401 Unauthorized (https://bz.pawdev.me/oauth/token)","stack":"","data":{"error":{"message":"No such session.","code":"NO_SUCH_SESSION","id":"5b5a1503-8bc8-4bd0-8054-dc189e8cdcb3","kind":"client"}}}

I think there is something wrong in the return url yall are passing.

Also I didnt post this as a issue (yet) cause calckey isnt officially supported by yall

Also spoiler, it seems to have something to do with how you cache requests or something like this, cause instead of ending up with my own user account, I now got logged into one of the testers' accounts. 🥴

Seems to be resolved in latest canary, thanks from us :)
