Uncaught (in promise) TypeError: Cannot assign to read only property 'lastMessage' of object '#<s>'

[Problem/Question]

Uncaught (in promise) TypeError: Cannot assign to read only property ‘lastMessage’ of object ‘#

When I called sendUserMessage

channel.sendUserMessage({ message: "Message" })

It returns

Uncaught (in promise) TypeError: Cannot assign to read only property 'lastMessage' of object '#<s>'

and no more working onMessageReceived of GroupChannelHandler in other users chat window.

It seems that sendbird sdk didn’t publish message to the websocket server when above error is occurred

[SDK Version]
