研究方向
Investigate the `M NOT FOUND` error when fetching room members for a federated invite. The error likely originates from token handling in the federation endpoint. Look at the `/ matrix/client/r0/rooms/{roomId}/members` handler and the federation module for event token validation. Check related discussions in other issues or PRs for similar fixes.
