Solve the following python programming problem given the following code:
@ app.route ('/VolumeDriver.Path', methods = ['POST']) 
@ _endpoint ('Path') 
def volumedriver_path(self, Name) : 
    "
        Return the path of a locally mounted volume if possible.

        Docker will call this in situations where it's not clear to us
        whether the dataset should be local or not, so we can't wait for a
        result.

        :param unicode Name: The name of the volume.

        :return: Result indicating success.
        " 
    d = DeferredContext (self._dataset_id_for_name (self)) 
    d.addCallback (self._get_path_from_dataset_id) 
    def got_path(path) : 
        if (path is None) :
