Python 尝试将保存的数据加载到新数据库时出现反序列化错误

因此，在我将数据库从sqlite更改为postgresql之前，我执行了

python manage.py dumpdata>datadump.json

，它在我的应用程序目录中保存了一个

datadump.json

文件和

dumpdata.json

文件

为了在我的新数据库中检索此数据，我执行了

python manage.py loaddata datadump.json

，但它返回了以下错误：

如果没有更多关于

datadump.json

的详细信息，这是不可能回答的。我在编辑中添加了一段

datadump.json

，因为它太大了，我无法全部添加。有什么具体的数据我可以给你提供更好的信息吗？
