错误消息：InvalidKey：密钥至少应包含一种

Question

尝试更新 google 云数据存储中的实体时出现以下错误：

InvalidKey: A key should contain at least a kind.
    at keyToKeyProto (/Volumes/Drive B/dev/zapi/node_modules/@google-cloud/datastore/src/entity.js:696:11)
    at Array.map (<anonymous>)

    at resolve (/Volumes/Drive B/dev/zapi/graphql/mutations/user/linkConsult.js:101:44)

我不知道这是为什么。

提前致谢。

Answer 1

当您尝试访问密钥时，当没有可用数据时密钥不可用，它会给出错误

"Error Message : InvalidKey: A key should contain at least a kind"

要避免此错误，请首先确保 [datastrore.KEY] 可用。

谢谢

我想在此答案中添加更多细节。如果您在使用 datastore.save 方法时运行遇到此错误，这里有一些其他有用的要点可以调查。实体需要正确的密钥属性，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)
