breeze - Metadata Error in Breeze after upgrade

Question

I have just upgraded to the latest version of breeze (1.3.5). I have code that is now failing that was working. The error:

Metadata import failed for /MyApi/PeopleOrg/Metadata; Unable to process returned metadata:Cannot read property 'name' of null

Here is what is returned by the call to get the Metadata (you will need to format this):

Any idea what could be causing this?

我想出了如何解决这个问题，但我不知道为什么需要它。我发现在处理 Person 类和 PersonPhoneNumber 类之间的关联时，微风代码失败了。我在 Person 类的 PhoneNumbers 属性上添加了实体框架 [InverseProperty("Phone")] 属性，并在 PersonPhoneNumber 类的 PersonId 属性上添加了 ForiegnKey("Phone") 指定，并添加了一个新的 Phone 类型的 Phone 属性在 PersonPhoneNumber 类中。

我想得到教训：确保在实体框架模型的两个类中明确定义关联端点。

当您在导入过程中遇到错误时，导入的元数据是使用先前版本的 Breeze 导出的吗？我问的原因是元数据可能出于各种原因从一个版本更改为另一个版本，其中一个原因是我们正在添加对 NoSQL 的支持并且它们具有新形式的元数据。

如果不是上述情况，您能否提供涉及问题的 2 个实体的定义以及您的导入/导出代码。通过这种方式，我们可以尝试在此处重现问题并进行修复，如果确定这是一个错误。

谢谢。
