Possible reason:

Room state not contains m.room.name, m.room.canonical_alias and room summary not contains any members.

room.data.state contains only this values:

The room.data.summary don't have m.heroes field at all:

{
  "m.joined_member_count": 1,
  "m.invited_member_count": 0
}

The `room.data.summary` don't have `m.heroes` field at all: ```json { "m.joined_member_count": 1, "m.invited_member_count": 0 } ```
