Does applying a 2dsphere index on a mongoose schema force the location field to be required?

Question

I have a mongoose schema and model defined as follows:

var mongoose = require(\'mongoose\')
  , Schema = new mongoose.Schema({
      email: {
        index:

By default, a property declared an array receives a default empty array to work with. MongoDB has started validating geojson fields and yells about empty arrays. The work around is to add a pre save hook to the schema that checks for this scenario and fixes up the document first.

schema.pre('save', function (next) {
  if (this.isNew && Array.isArray(this.location) && 0 === this.location.length) {
    this.location = undefined;
  }
  next();
})
