You're not passing in a schema to your configuration for the /graphql endpoint.
Property names are case-sensitive in javascript. Change this:
*/
app.use('/graphql',bodyParser.json(), graphqlExpress({
  Schema,
  context:{
    Story,
    User
  }
}))
// to this:

app.use('/graphql',bodyParser.json(), graphqlExpress({
  schema: Schema,
  context:{
    Story,
    User
  }
}))

// or make your variable lowercase and then do:

app.use('/graphql',bodyParser.json(), graphqlExpress({
  schema,
  context:{
    Story,
