**[Problem/Question]**

I’m trying to select a room in a group channel and send a chat, but I keep getting an error in sendUserMessage.

For example, I used the code below.

currentlyJoinedChannel  
.sendUserMessage({  
message,  
})  
.onSucceeded((message: string) =\> {  
…  
})  
.onFailed((error: any) =\> {  
…  
});

We see that the currentJoinedChannel has a value. Why doesn’t it?

Do I need any additional settings to send a chat?
