Persistent queries issue with GraphQLi error

The new code added in the persistent queries commit https://github.com/sysgears/apollo-fullstack-starter-kit/commit/de2fdec1e0182bb949ac89020c8d2f0298c72946 breaks GraphQLi.

TypeError: req.body.map is not a function

The following code in src/server/api_server assumes that all req.body are arrays.

app.use(
    '/graphql',
    (req, resp, next) => {
        req.body = req.body.map(body => {
          return {
            query: invertedMap[ body.id ],
            ...body
          };
        });
      next();
    },
  );

I have not investigated what is involved with persistent queries so I cannot say this fix is correct, but this does protect the map from getting called on a non-array:

import { invert, isArray } from 'lodash';
...
app.use(
    '/graphql',
    (req, resp, next) => {
      if (isArray(req.body)) {
        req.body = req.body.map(body => {
          return {
            query: invertedMap[ body.id ],
            ...body
          };
        });
      }
      next();
    },
  );

@vlasenko I think this ok. As long as you can still use GraphQL in dev mode this is fine with me.

Nope not working. Fresh started. Go to graphiql by the button up right corner. Try to get post with Id.
