When used as specified in the middleware documentation, the function is executed for every type, for every field of that type, and for all subfields in the request.

I installed the package as directed in readme. And Launched the first example https://github.com/maticzav/graphql-middleware#how-does-it-work.

I expected to see something similar during execution, which is indicated in the diagram. 2 messages before the resolver, 2 after.
However, my entire console was filled with messages for the request itself, for return type fields, for all subfields of that type.

Is this the right job?

server:

const { ApolloServer, makeExecutableSchema } = require('apollo-server');
const { applyMiddleware } = require('graphql-middleware');
const { typeDefs, resolvers } = require('./modules');
const schemaDirectives = require('./directives');

const executableSchema = makeExecutableSchema({
  typeDefs,
  resolvers,
  schemaDirectives,
})

const logInput = async (resolve, root, args, context, info) => {
  console.log(`1. logInput: ${JSON.stringify(args)}`)
  const result = await resolve(root, args, context, info)
  console.log(`5. logInput`)
  return result
}

const logResult = async (resolve, root, args, context, info) => {
  console.log(`2. logResult`)
  const result = await resolve(root, args, context, info)
  console.log(`4. logResult: ${JSON.stringify(result)}`)
  return result
}

const schema = applyMiddleware(executableSchema, logInput, logResult);

const server = new ApolloServer({
  schema,
  context: req => {
    return {
      ...req,
    }
  }
});

server.listen({
  port: APP_PORT,
}).then(({ url }) => {
  console.log(`🚀 Server ready at ${url}`);
});

query:

query getOneDashboard($where: DashboardWhereUniqueInput!) {
  data: Dashboard(where: $where) {
    item {
      ...DashboardFragment
