Mongoose validation error - what is it telling me? - node.js

Question

I'm trying to use a JSON file to populate my DB - I've had success with some other files, but this file / model is throwing validation errors and the errors aren't very helpful to me - They say there is a validation error, they even kinda tell me that it's at a forEach line in the schematype.js file - but I'm not gonna go and change a file in the node-modules folder...especially when I think it's my coding fault.
"mongoose": "4.9.8"
This is in the APP.JS - which calls /loaddata:
app.get('/api/loadData', (req, res) => {
var Xs = require( './_mock_data/x.json' );
for ( var i in Xs ) {
X.create( Xs[i] );
console.log( Xs[i] );
};
});
This is in my model page:
const XSchema = mongoose.Schema({
name:{
type: String,
required: true
},
state:{
type: String
},
type:{
type: String
},
people:{
type: [mongoose.Schema.Types.Mixed]
},
create_date:{
type: Date,
default: Date.now
}
});
My JSON file looks like this - I think the offending data is the "people" with a Mixed type - my confusion comes with the fact that it IS an array of people, so the forEach should loop it - why is it failing?
[
{
"name": "Building One",
"state": "Alaska",
"people": [{
"position": "Chair",
"department": "Sales",
"email": "aftcs#blah.io",
"phone": "",
"name": "John Smith"
}],
"type": "Business"
}, {
"name": "Fairbanks Folly",
"state": "Maine",
"people": [{
"position": "Sitting",
"department": "AAA",
"email": "ffjda#uafert.com",
"phone": "",
"name": "Jane Aspnes"
}, {
"position": "Standing",
"department": "BBB",
"email": "jmbicigo#Maine.com",
"phone": "",
"name": "James Bicigo"
}, {
"position": "Lying",
"department": "AAA",
"email": "kmbutlerhopkins#Craf.org",
"phone": "",
"name": "Kam Butler-Hopkins"
}],
"type": "Other"
}
]
And lastly - the ERROR -
Unhandled rejection ValidationError: College validation failed

Again, any help and insight is much appreciated!
