Test on param_value changes as follows:

            # If the parameter wasn't found and it was required, return 400
            if param_value is None and param['required']:
                msg = ("Failed to parse request. " +
                       "Parameter: " + param_name + " not specified")
                for line in msg.split('\n'):
                    LOG.error(line)
                raise exc.HTTPBadRequest(msg)
