"MongoError: '$setOnInsert' is empty" when using more than one Boolean-type field in AutoForm

[mishantidev]

Getting an error in client console:

MongoError: '$setOnInsert' is empty. You must spec…y a field like so: {$setOnInsert: {: ...}}

I have two Boolean checkboxes in my form. If I remove one of them from the form, it works correctly ("animate" and "hasLink" fields).

Autoform 6.3.0, Meteor 1.6.1

Schema:

import { ElementImages } from './element_images.js'
import SimpleSchema from 'simpl-schema'

SimpleSchema.debug = true

SimpleSchema.extendOptions(['autoform'])
SimpleSchema.setDefaultMessages({
  initialLanguage: 'en',
  messages: {
    en: {
      uploadError: '{{value}}', //File-upload
    },
  }
})

export const Elements = new Mongo.Collection("Elements")

Elements.schema = new SimpleSchema({
  pageId: {
    type: String,
    label: 'Page Id',
    defaultValue: () => { return FlowRouter.current().route.name }
    // autoform: {
    //   type: 'select',
    //   // options() { return selectOptions(Pages) }
    // }
  },
  type: {
    type: String,
    label: 'Type',
    autoform: {
      options: {image: 'Image', imageSlider: 'Image Slider'}
    }    
  },
  width: {
    type: Number,
    label: 'Width, px',
    optional: true
  },
  height: {
    type: Number,
    label: 'Height, px',
    optional: true
  },
  imageId: {
    type: String,
    label: 'Image',
    optional: true,
    autoform: {
      afFieldInput: {
        type: 'fileUpload',
        collection: 'ElementImages',
        // uploadTemplate: 'uploadField', // <- Optional
        // previewTemplate: 'uploadPreview' // <- Optional
      }
    }
  },
  hasLink: {
    type: Boolean,
    defaultValue: false,
    optional: true
  },
  linkAddr: {
    type: String,
    optional: true,
    label: 'Link address'
  },
  animate: {
    type: Boolean,
    defaultValue: true,
    optional: true
  },
  animationType: {
    type: String,
    label: 'Animation Type',
    optional: true,
    autoform: {
      type: 'select',
      options: {fadeIn: 'Fade in', slideInDown: 'Slide from top', slideInUp: 'Slide from bottom', slideInLeft: 'Slide from left', slideInRight: 'Slide from right'},
      defaultValue: 'fadeIn'
    }
  },
  animationDelay: {
    type: Number,
    label: 'Animation Delay, ms.',
    defaultValue: 0,
    optional: true
  }
})

Elements.attachSchema(Elements.schema)

Form:

        if Template.subscriptionsReady
