When connecting a user for the first time, the response from the api is error since the user does not exist. This is fine because when connect is called for the first time for a user, it first tries to obtain the user's encrypted keys from the blindnet system. If it fails, the SDK assumes the user is not in the blindnet system and calls the endpoint to register a new user.
However, this error will show in the browser network and might confuse the user.
