Introspection query is run at the wrong url

Question

I have a Serverless project with Apollo graphql lambda endpoint at url like:

https://w040io5bk9.execute-api.us-east-1.amazonaws.com/dev/graphql

When I go to it, I get the Playground UI. However, when it runs it's introspection query, it runs it at a wrong url:

https://w040io5bk9.execute-api.us-east-1.amazonaws.com/graphql

Notice the /dev is missing.

What sort of misconfiguration might I have done here?

Answer 1

I was able to fix this by providing endpoint in the ApolloServer config:

    playground: {
      endpoint: 'graphql'
    }

Doesn't make much sense to me either : /
