apollo-link-state cache.writedata导致缺少字段警告

Question

当我在客户端上调用变异时,我收到以下警告:

writeToStore.js:111 {}中缺少字段updateLocale

这是我的stateLink:

const stateLink = withClientState({
  cache,
  resolvers: {
    Mutation: {
      updateLocale: (root, { locale }, context) => {
        context.cache.writeData({
          data: {
            language: {
              __typename: 'Language',
              locale,
            },
          },
        });
      },
    },
  },
  defaults: {
    language: {
      __typename: 'Language',
      locale: 'nl',
    },
  },
});

这是我的组成部分:

export default graphql(gql`
  mutation updateLocale($locale: String) {
    updateLocale(locale: $locale) @client
  }
`, {
    props: ({ mutate }) => ({
      updateLocale: locale => mutate({
        variables: { locale },
      }),
    }),
  })(LanguagePicker);

我错过了什么？

我得到了同样的警告并通过从变异方法返回数据来解决它.

updateLocale: (root, { locale }, context) => {

  const data = {
    language: {
      __typename: 'Language',
      locale,
    }
  };
  context.cache.writeData({ data });
  return data;
};
