Yes, and I'm using jellyfin-sdk-kotlin

    val jellyfin = Jellyfin {
        clientInfo = ClientInfo("Jellyfin CLI", "DEV")
        deviceInfo = DeviceInfo("developer", "developer")
    }

    val api = jellyfin.createApi(baseUrl = server, accessToken = "xxxxxxxxxx")
    val session = SessionApi(api).getSessions().content.firstOrNull()
    api.userId = session?.userId

Have you tried it with a user ID? The API has lots of inconsistencies in that regard at the moment, so it might be required.

I have tried to use /Users/{userId}/Items, and pass userId to /Items

they are both worked.

@nielsvanvelzen commented on GitHub (Jun 22, 2021):

Some tips:

  • When authenticating using the API with for example AuthenticateUserByName you can get the user id from that response, no need for the sessions call
  • When using the ItemsApi use the GetItemsByUserId function instead of GetItems. They both use the exact same code path in the server but the second one marks the user id (wrongly) as nullable and the SDK won't automatically fill it in.

Seems like this has been "resolved". It's also a duplicate of https://github.com/jellyfin/jellyfin/issues/2246.
