Using a Map field

[MDrooker]

I have a schema that looks like -

let jobSchema = mongoose.Schema({
            jobuuid: { type: String },
            type: { type: String },
            jobDetails: { type: Types.Mixed },
            jobOptions: {
                type: Map,
                of: JobOptionsSchema
            },
        })

And trying to use a mutation that looks like -

mutation{
  createJob(record:{jobOptions:{name:"demo"}}){
    recordId
  }
}

But im getting an error-

{
  "errors": [
    {
      "message": "job validation failed: jobOptions: Cast to Map failed for value \"[Object: null prototype] { name: 'matthew' }\" at path \"jobOptions\"",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "stack": [],
      "path": [
        "createJob"
      ]
    }
  ],
  "data": {
    "createJob": null
  }
}

Did something change with how to use the Map field?

Nope, everything stays the same from the last PR https://github.com/graphql-compose/graphql-compose-mongoose/commit/eecf9eab1b09b05f19ec67d24b7ccb35d06e00f8

Maybe something changed in mongoose?! But how I see today tests passed successfully - https://travis-ci.org/github/graphql-compose/graphql-compose-mongoose/builds/716152379

@MDrooker can you open PR with a broken test in this folder for your issue https://travis-ci.org/github/graphql-compose/graphql-compose-mongoose/builds/716152379 ?

Is it just that the GraphQL syntax for declaring the Map is wrong? Here's a barebones use of Mongoose's Map SchemaType, adapted from the big group example in the Mongoose docs:

const schema = new Schema({
  map: Map
});
const Thing = mongoose.model('Thing', schema);
const m = new Thing;
m.map = new Map([['key', 'value']]);

Note the list-of-tuples style of initialisation. I was having the same problem as MDrooker, but then found that the list-of-tuple syntax works from the GraphQL side, as opposed to object syntax:

mutation {
  createJob( record: { jobOptions: [["name", "demo"]] }) {
    recordId
  }
}

The only problem I noticed then was that I could give any value, as it doesn't seem to validate against the desired schema for the of field. It only fails to cast on bad values if I use a simple type like String or Number. But this schema validation issue seems like it would be a Mongoose problem, rather than one with graphql-compose-mongoose.
