graphql-server-lambda - graphiql not compatible with nodejs8.10 runtime

[nenti]

graphiql handler is failing with no error message thrown when changing lambda runtime to nodejs8.10

[dhm116]

We're running graphiql with the nodejs8.10 runtime without any issues that we're aware of - are you able to provide any snippets demonstrating the issue?

Aside from the serverless configuration, this is all we needed to enable graphiql to work with serverless and serverless-offline:

// Avoid using async/promises until apollo-server-lambda/apollo-server-core
// are updated to support async/await
exports.graphiqlHandler = (event, context, callback) => {
  const graphqlHandler = graphiqlLambda({ endpointURL: '/graphql' });
  return graphqlHandler(event, context, callback);
};

My failing handler looks like this. Node6 workd node8 fails. Interesting.

return server.graphiqlLambda({
    endpointURL: GRAPHQL_ENDPOINT,
    passHeader: event.queryStringParameters && event.queryStringParameters.auth,
})(event, context, callback)

Yeah, that looks very similar....as I mentioned, we're using serverless and deploying to AWS, so here is a representative portion of that config in case it helps:

service: example

provider:
  name: aws
  runtime: nodejs8.10
  region: us-west-2
  profile: user-profile
  stage: ${self:custom.stage}
  endpointType: REGIONAL

package:
  individually: true
  excludeDevDependencies: true

plugins:
  - serverless-webpack
  - serverless-mocha-plugin
  - serverless-offline

custom:
  # Plugin Config
  webpack:
    includeModules:
      forceExclude:
        - aws-sdk
    packager: npm
  serverless-offline:
    port: 4000

functions:
  graphql:
    name: ${self:provider.stage}-graphql
    description: GraphQL Handler (GET/POST /graphql)
    handler: graphql/index.handler
    warmup: production
    events:
      - http:
          path: graphql
          method: post
      - http:
          path: graphql
          method: get
  graphiql:
    name: ${self:provider.stage}-graphiql
    description: GraphiQL Handler (GET /graphqli)
    handler: graphql/index.graphiqlHandler
    events:
      - http:

          method: get

I was using Node 8.11 in Lambda with this configutation, and worked perfectly

module.exports.graphiQL = server.graphiqlLambda({		
  endpointURL: '/graphql',		
})

functions
  graphiql:		
    handler: handler.graphiQL		
      events:		
        http:
            path: graphiql
            method: get

I'm going to close this, since it seems we've figured out the issue and #1125 is out!

Is it possible to use graphiql with apollo-server2 or only playground?

I get TypeError: server.graphiqlLambda is not a function
