Ошибка: финальный загрузчик не вернул буфер или строку

Question

Я преобразовал свой запрос GraphQL и компонент HOC в машинописный текст, и теперь получаю следующую ошибку:

ERROR in ./client/components/Protected.Route.tsx

Я перепробовал почти все, что нашел в Интернете.allowJs установлен в true в tsconfig.Мы будем благодарны за любую помощь.

Версии:

Машинопись: 3.1.6

Веб-пакет: 4.29.3

загрузчик: 5.2.1

Это код для Protected.Route.tsx:

import * as React from 'react';
import { Route, Redirect, RouteProps } from 'react-router-dom';
import { Query } from 'react-apollo';
import currentUserQuery from '../graphql/queries/currentUser';

interface ProtectedRouteProps extends RouteProps {
  component: React.ComponentType<RouteProps>;
}

const ProtectedRoute = ({ component: Component, ...rest }: ProtectedRouteProps) => (
  <Route
    {...rest}
    render={props => {
      <Query query={currentUserQuery}>
        {({ loading, data: { currentUser } }) => {
          if (loading) return null;
          if (currentUser) {
            return <Component {...props} />;
          }
        }}
      </Query>;
      return (
        <Redirect
          to={{
            pathname: '/login',
            state: {
              from: props.location
            }
          }}
        />
      );
    }}
  />
);

export default ProtectedRoute;

И код для currentUser.ts:

import { gql } from 'apollo-boost';

export default gql`
  {
    currentUser {
      id
      email
      name
    }
  }
`;

webpack.config.js

module.exports = {
  entry: './client/index.js',
  output: {
    path: '/',
    filename: 'bundle.js'
  },
  module: {
    rules: [
      {
        use: 'babel-loader',
        test: /\.jsx?$/,
        resolve: {
          extensions: ['.ts', '.tsx', '.js', '.jsx', '.json']
        },
        exclude: /node_modules/
      },
      {
        test: /\.tsx?$/,
        loader: 'awesome-typescript-loader',
        options: {
          getCustomTransformers: () => ({ before: [styledComponentsTransformer] })
        }
      }
    ]
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: 'client/index.html'
    })
  ]
};

Обновите файл tsconfig.json, включив в него следующий код:

"awesomeTypescriptLoaderOptions": {
"useWebpackText": true,
"useTranspileModule": true,
"doTypeCheck": true,
"forkChecker": true

}
