参考输入不适用于自定义dataProvider，React-admin

Question

我正在尝试将<ReferenceInput>元素与自定义数据提供程序结合使用，并收到此错误：

缺少键的翻译：“ dataProvider未定义”

即使我的数据提供者看起来像这样，也会发生：

import jsonServerProvider from "ra-data-json-server";
import { adminPageTokenFetch } from "APIServices/CRUD";

const dataProvider = jsonServerProvider("/api", adminPageTokenFetch);

export const myDataProvider = {
  ...dataProvider
}

使用<ReferenceInput>的组件示例：

export const SessionEdit = (props: any) => {
  return (
    <Edit {...props}>
      <SimpleForm>
        <ReferenceInput source="film" reference="films">
          <SelectInput optionText="name" />
        </ReferenceInput>
        <DateInput source="dateTime" />
        <NumberInput source="price" />
        <ReferenceInput source="genre" reference="genres">
          <SelectInput optionText="name" />
        </ReferenceInput>
      </SimpleForm>
    </Edit>
  );
};

这是我的索引页：

export const AdminPage = (props: { lang: string }) => {
  const messages = {
    ru: russianMessages,
    en: englishMessages
  } as any;

  return (
    <Provider store={createAdminStore({ myDataProvider, history })}>
      <Admin
        dataProvider={myDataProvider}
        history={history}
        title={props.lang === "ru" ? "Админ панель" : "My admin"}
        i18nProvider={polyglotI18nProvider(() => messages[props.lang])}
      >
        <Resource
          name="sessions"
          list={SessionList}
          edit={SessionEdit}
          create={SessionCreate}
        />
        <Resource name="translations" list={TranslationList} />
      </Admin>
    </Provider>
  );
};

这里是createAdminStore函数：

export default ({ dataProvider, history }: any) => {
  const reducer = combineReducers({
    admin: adminReducer,
    router: connectRouter(history)
  });

  const saga = function* rootSaga() {
    yield all([adminSaga(dataProvider)].map(fork));
  };
  const sagaMiddleware = createSagaMiddleware();

  const store = createStore(
    reducer,
    compose(applyMiddleware(sagaMiddleware, routerMiddleware(history)))
  );
  sagaMiddleware.run(saga);
  return store;
};

UI上的外观：

其他组件仍然可以正常工作。

默认情况下，每次调用时，polyglotI18nProvider都会在console中记录一条警告，并带有一条当前翻译中找不到的消息。
