return (
<div>

I actually had a similar problem yesterday. Googling around it actually led me here. Eventually, I found a way around it.
So, the first thing I do after creating the connection to SendBird is to create a connection for that user I wish to connect to.
var sb = new SendBird({
appId: 'YOUR SENDBIRD APP ID HERE'
});
sb.connect(UNIQUE_USER_ID, function(user, error) {
connectToUser();
});
function connectToUser(){
sb.connect(YOUR_OWN_USERID, function(user, error) {
sb.GroupChannel.createChannelWithUserIds([UNIQUE_USER_ID], true, UNIQUE_USER_ID+YOUR_OWN_USERID, '', '', '', function(createdChannel, error){
$scope.chatChannel = createdChannel;
if (error) {
console.log(error);
return;
}
});
});
}
Then, you can proceed to send your messages using the createdChannel
$scope.chatChannel.sendUserMessage(YOUR_MESSAGE_HERE, '', '', function(message, error){
if (error) {
console.error(error);
return;
}
console.log(message);
});
Let me know if that works.
