Unable to replicate channel other than "*"

Hi,
I use the following:

{
    "log":["CRUD+", "REST+", "Changes+", "Attach+"],
    "databases": {
        "contacts":{
                   "server":"http://localhost:8091",
                    "bucket":"_contacts",
                 "sync":`function(doc) {
                access("nu", "nu");
                channel("nu_alt");                
                 }`,
            "users":{
            },
            "shadow":{
                "server":"http://localhost:8091",
                "bucket":"contacts"
            }
        }
    }
}

to isolate the replication of channel “nu” for user named “nu”.
But i get:

MultiChangesFeed: channels expand to channels.TimedSet{"!":0x1, "vj":0x2a, "vj_alt":0x2b} ...   (to nu)      ...and so on

the user nu has the following config (registered with sync gateway):

{"name":"nu","admin_channels":["nu"],"all_channels":["!","nu"]}

What am i doing wrong?
Thanks

I’m not entirely clear on what your issue is.

If all your users are seeing docs in all channels, try the following:

Disable the GUEST user:

"users": {
        "GUEST": {"disabled": true}
      },

And make sure your client is connecting to port 4984 which will require them to authenticate.

Sorry if i’m not clear.
I added the “GUEST” line, but i still get:
