GroupChannel sendUserMessage - SendbirdError: Invalid parameters


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.

.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?
