Here's a reference setup of AWS Lambda and Serverless and GraphQL that i'm following:
https://github.com/serverless/serverless-graphql-apollo
I'm trying with yarn run start-server-lambda:offline to start the project offline, it does start without any problems, but upon navigating to /graphiql, I get this:

There's a configuration problem somewhere.
Basically, it's sending a request to
/production/graphqlwhen it should have been sending it to/graphql.
