上传文件时遇到问题。当我上传一个大于30mb的文件时，我收到错误消息
“413 payload too large”.
直到现在我仍然无法解决。
下面是我的代码。

import { ApolloServer, AuthenticationError } from "apollo-server";
const server = new ApolloServer({
  typeDefs,
  resolvers,
  uploads: {
    maxFileSize: 50000000, // 50 MB
    maxFiles: 30,
    maxFieldSize: 50000000 // 50 MB
  },
  dataSources,
  introspection: !(process.env.ENVIRONMENT == "PRODUCTION"),
  playground: !(process.env.ENVIRONMENT == "PRODUCTION")
});
server.listen().then(({ url, subscriptionsUrl }) => {
  console.log(`Server ready at ${url}`);
});

期待得到大家的帮助。
