Json validation for my db update/upsert operations keeps failing. Updates are only successful when I remove the db.createCollection validator option parameter. But schema validation is crucial for this use-case so development is currently at a halt and 3 days have been lost as a result. 
 
Schema

 {
    additionalProperties: false,
    bsonType: 'object',
    description: 'email data point',
    properties: {
        _id: {
            bsonType: 'objectId'
        },
        address: {
            bsonType: 'string',
            maxLength: 64,
            pattern: '^\w+@\w+(.\w+)+$',
            description: 'required: email address'
        },
        contactTypes: {
            bsonType: 'array',
            description: 'required: a set of unique string values',
            items: {
                bsonType: 'string',
                enum: email.map( e => e.value )
            },
            uniqueItems: true
        },
        dateCreated: {
            bsonType: 'long',
            description: 'required: contact email creation timestamp in ms since epoch'
       },
        isPrimary: {
            bsonType: 'bool'
       },
        lastUpdated: {
            bsonType: 'long',
            description: 'contact email recent update timestamp in ms since epoch'
        }
    },
    required: [ 'address', 'contactTypes', 'dateCreated', 'isPrimary' ]
}{{}}

 
Shell call:
 MongoDB Enterprise D0-shard-0:PRIMARY> db.emails.findOneAndUpdate({
address: 'adfadfslkds@ffk.co.uk',
contactTypes: [ 'p', 'b' ],
isPrimary: true
}, {
$set:

}, {
returnNewDocument: true,
upsert: true
})
 
Result:

Thanks in advance for looking into this issue.
