Remote schema, node-fetch example, unexpeced colon

[mikaelkundert]

On Remote schemas docs we have an example for using node-fetch:

import fetch from 'node-fetch';
import { print } from 'graphql':

const fetcher = async ({ query: queryDocument, variables, operationName, context }) => {
  const query = print(queryDocument);
  const fetchResult = await fetch('http://api.githunt.com/graphql', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({ query, variables, operationName })
  });
  return fetchResult.json();
};

export default async () => {
  const schema = makeRemoteExecutableSchema({
    schema: await introspectSchema(fetcher),
    fetcher,
  });
  return schema
}

Line 2 ends with : and doesn't work.
