Csharp Newtonsoft.Json.JsonSerializationException：从Castle.Proxies.SalonProxy上的MyEntity获取值时出错

Hi everyone,我有Asp.使用实体框架Core 6.0和Postgresql作为数据库的Net Core Web API项目

我配置了实体及其关系.一切都很好，但通用存储库设计模式中只有一个问题

如果我只使用context.Products.ToList()，它就工作得很好.但每当我将其与通用存储库设计模式一起使用时.我出错了.但有一件有趣的事.无论何时，只要我使用断点10秒或更长时间，并且在10秒后保持断点，都不会出现错误.一切都很完美.是否存在异步问题，我从未使用过它？
