Update socket.data value when using cluster adapter

[hysapp]

Before I used the cluster adapter, I updated the socket data as follows:
let user = new User(......)
let sockets = await io.in(user.uid).fetchSockets();
for (let i = sockets.length - 1; i >= 0; i--) { sockets[i].data.user = user; }

Then when I called the fetchSockets() elsewhere, the socket data had changed.

But now when I use the cluster adapter, the socket data does not change.
How can I do this without disconnecting the socket?
