Error: Query root type must be provided

I seem to be getting this error:

https://github.com/prismagraphql/graphql-import/issues/73

I’m running 0.0.10, with a schema generated by graphql-cli from a gatsby project:

# source: http://0.0.0.0:8000/___graphql
# timestamp: Sat Jul 28 2018 17:46:31 GMT+0000 (Greenwich Mean Time)

schema {
  query: RootQueryType
}

"""
A date string, such as 2007-12-03, compliant with the ISO 8601 standard  for
representation of dates and times using the Gregorian calendar.
"""
scalar Date

# ...

Here’s the full error:

(node:15016) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Query root type must be provided.
(node:15016) DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

No stack trace, unfortunately.

const WAUsers = require(‘…/models/wibesAppUsers’); //this is mongodb model

const wAUType = new GraphQLObjectType({ name:‘wAP’, e fields:() => ({ human_name:{type:GraphQLString}, pass_code:{type:GraphQLString}, }) });

const Mutation = new GraphQLObjectType({ name:‘Mutation’, fields:{ addWAUser:{ wAUType, args:{ human_name:{type:new GraphQLNonNull(GraphQLString)}, pass_code:{type:new GraphQLNonNull(GraphQLString)}, }, resolve(parent,args){ let user = new WAUsers({ human_name:args.human_name, pass_code:args.pass_code, }); return user.save(); } } } } })

module.exports = new GraphQLSchema({ mutation:Mutation });

i am importing mongodb model and inserting into it using graphql schema
