我在尝试更新google云数据存储中的实体时遇到以下错误:

InvalidKey: A key should contain at least a kind.

我不知道为什么会这样。

提前谢谢。

为了避免这个错误,首先确保[数据仓库.KEY]是可用的。

我想对这个答案再加上一点细节。如果在使用数据存储.save方法。实体需要正确的key属性,如下例所示。

// remember to use the key method on the google data store instance
const entity = {
  key: dataStore.key('Name of your Kind') // this is Kind property you see on the GCP dashboard,
  data: {
    example: 'this is an example',
    ...
  }
};

// then save the entity
const dbResult = await dataStore.save(entity)
