itchat.send_msg returns -1.

The application seems broken and returns -1 without any error message upon an attempt to send a message.

itchat.send_msg('Hellouser', toUserName='user')
<ItchatReturnValue: {'BaseResponse': {'Ret': -1, 'ErrMsg': '', 'RawMsg': ''}, 'MsgID': '', 'LocalID': ''}>

Never get this error though, Is 'user' a real value or just an example of something like 'Anna', 'Jack' ?

[markovejnovic]

Real user. I will retry using the library to make sure it was not my error.
