Playground not loading on Serverless with Lambda Middleware version 1.3.6

This issue pertains to the following package(s):

• GraphQL Playground - Electron App
• GraphQL Playground HTML
• GraphQL Playground
• GraphQL Playground Express Middleware
• GraphQL Playground Hapi Middleware
• GraphQL Playground Koa Middleware
• GraphQL Playground Lambda Middleware

What OS and OS version are you experiencing the issue(s) on?

Ubuntu 16.04 and Windows 10

What version of graphql-playground(-electron/-middleware) are you experiencing the issue(s) on?

graphql-playground-middleware-lambda 1.3.6

What is the expected behavior?

The playground should load as usual.

What is the actual behavior?

On Servless Offline you get

{"domain":{"domain":null,"_events":{},"_eventsCount":1,"members":[]}}

or on AWS you get

{"message": "Internal server error"}

What steps may we take to reproduce the behavior?

1. Remove yarn.lock in either graphql-playground-middleware-lambda/examples/basic or serverless-graphql/app-backend/rest-api
2. Run yarn install or npm install
3. Start with serverless deploy

This should be fixed with graphql-playground-middleware-lambda@1.3.9 ✅

I think I am facing an issue related to this, I am working on an example with following dependencies:-

"graphcool-binding": "1.3.1",
"graphql-yoga": "1.1.1",

The GraphQLServer from graphql-yoga gets a working middleware path - http://cdn.jsdelivr.net/npm/graphql-playground-react@1.3.20/build/static/js/middleware.js

But GraphQLServerLambda from graphql-yoga gets me a 404 middleware path - http://cdn.jsdelivr.net/npm/graphql-playground-react@1.3.7/build/static/js/middleware.js

I tried to setup this on local to attempt a fix (by tinkering graphql-playground-html version) by linking graphql-yoga, graphql-playground to in order but I think I am missing something there.

Also, I wanted to know why do we have different packages in graphql-playground, do they need to be linked separately for development? What are the upsides of doing it in this way over say having one release for graphql-playground itself and whenever a sub-package changes, we can bump up the version of graphql-playground. Just curious about the though process behind current structure.
