although if there is any available room it worked just fine and join that room. problem occurs when there is no room available to join (should not it automatically create a room ?)

here's server onJoin method

requestJoin (options, isNew) {
console.log("request join!", options);
return (options.create)? (options.create && isNew) : this.clients.length > 0;
}
onJoin (client, options) {
console.log("client joined! ", options);
}

Unity client code

string roomName = "table"
//for Quick Join
public void Join()
{
room = client.Join(roomName, new Dictionary<string, object>()
{
{ "create", false}
});
StartCoroutine(ConnectToRoom());
}
//for Creting new room
public void Create()
{
Debug.Log("Let's Crete & join the room!");
room = client.Join(roomName, new Dictionary<string, object>()
{
{ "create", true },
});
StartCoroutine(ConnectToRoom());
}

You may modify the requestJoin method to allow creating the room regardless of the param create is being passed as true or not. I've made this example to demonstrate that clients may have control to create or join into rooms. By omitting the requestJoin method, it will always return true.
