There could be a few reasons why the result of socket.adapter.rooms in Socket.io is returning an empty array even though data is present:
The data may not have been properly added to the room. When a socket joins a room, the room is only created if it did not previously exist. If the socket disconnects from the room and there are no other sockets left, the room will be destroyed. It's possible that the data was not properly added to the room, or the room was destroyed before the result was returned.
The data may not have been properly retrieved from the room. Even if the data is present in the room, Socket.io may not have been able to retrieve it properly due to an error in the code or configuration.
The data may be stored in a different format than expected. Socket.io stores data in a hierarchical structure based on rooms and sockets. If the data is not in the expected format or location, Socket.io may not be able to retrieve it properly.
To troubleshoot the issue, you can try logging the data and the result of socket.adapter.rooms to see if there are any discrepancies or errors. Additionally, you can check for any errors in your code or configuration that may be preventing the data from being properly retrieved.
