Issuing token for user results in error "Something went wrong"

Hey guys!

I have integrated Sendbird chat into our website. For now, we don’t indicate when there is a new message, but we want to show a notification. Accordingly, I want to add web socket to get new messages and do it by getting a token for the user. However, when I press the button “issue” to get a token, my user gets “deactivated”, so it just shows error “Something went wrong” instead of chat.

Could you please help me with this?
