Solve the following python programming problem given the following code:
@ tornado.gen.coroutine 
def _crypted_transfer(self, load, tries = 3, timeout = 60) : 
    '
        In case of authentication errors, try to renegotiate authentication
        and retry the method.
        Indeed, we can fail too early in case of a master restart during a
        minion state execution call
        ' 
    @ tornado.gen.coroutine 
    def _do_transfer() : 
        data = (yield self.message_client.send (self._package_load (self.auth.crypticle.dumps (load)), timeout = timeout)) 
        if data : 
            data = self.auth.crypticle.loads (data) 
            if six.PY3 : 
                data = salt.transport.frame.decode_embedded_strs (data) 
raise tornado.gen.Return (data) 
if (not self.auth.authenticated) : 
        (yield self.auth.authenticate ()) 
try : 
        ret = (yield _do_transfer ()) 
        raise tornado.gen.Return (load) 
except salt.crypt.AuthenticationError : 
        (yield self.auth.authenticate ()) 
        ret = (yield _do_transfer ()) 
        raise tornado.gen.Return (ret) 

    
    

    Fix the buggy line: raise tornado.gen.Return (load)

#Here is Python program to fix the buggy line: raise tornado.

raise tornado.gen.Return (ret)
