foxy下使用自定义msg并录制ros2 bag。python3.8下载安装ros2bag-convert，source环境接口后，使用命令ros2bag-convert xxxx.db3转换，报错如下：

@刚刚小飞机 在 [foxy][ros2bag-convert]转换msg失败 中说：
message_fields = message.get_fields_and_field_types()AttributeError: 'list' object has no attribute 'get_fields_and_field_types'
把这个消息打印出来看看具体内容先,估计是我内部处理有一些小bug
