sometimes going not ready just hands with no response on the websocket of the JS SDK not any logs are written on the CCTServer log files

this happens with many other methods as well, updating customer Email, updating customer address, changing after work code, etc.
also the documentation of the SDK is weak, there are lots of incorrect functions declarations, lice udpateCustomerEmail it says it accepts a string, while if you open it in the SDK js file, it accepts a callback, customer id, and email object, but still it is not working.....
