Fetching an invited room through the RoomListService fails #3848

Open stefanceriu opened 3 months ago

stefanceriu commented 3 months ago

Using the RoomListService to fetch a room by id, where that room is in the invited state has regresed and is now failing with

RoomListError
  ▿ InitializingTimeline : 1 element
    - error : "The room\'s encryption state is unknown."

This was introduced in https://github.com/matrix-org/matrix-rust-sdk/commit/bae0f304f7efc3c6a34d2ca805eb2d4b27189ce9#diff-dff33932423bfedc588739ae79f87f64f063a52aada9483069fb11bc5487c3b7R161-R162

Turns out this is not necessarily a rust bug. The client asks to initialise the timeline when fetching a room and actually what's wrong over here. We'll switch away from that and not change anything on the rust side.

Reopening this as it can't be solved on the client side only. Using full_room on a roomListItem on which the timeline hasn't been initialized failes as per https://github.com/matrix-org/matrix-rust-sdk/blob/main/bindings/matrix-sdk-ffi/src/room_list.rs#L616

The "full_room" is used to accept or decline and invite.
