How to use the loopback-datasource-juggler/lib/geo.GeoPoint function in loopback-datasource-juggler

// For numbers, only convert it produces a valid number
      // LoopBack by default injects a number id. We should fix it based
      // on the connector's input, for example, MongoDB should use string
      // while RDBs typically use number
      DataType = NumberType;
    }

    if (!DataType) {
      continue;
    }

    if (DataType.prototype instanceof BaseModel) {
      continue;
    }

    if (DataType === geo.GeoPoint) {
      // Skip the GeoPoint as the near operator breaks the assumption that
      // an operation has only one property
      // We should probably fix it based on
      // http://docs.mongodb.org/manual/reference/operator/query/near/
      // The other option is to make operators start with $
      continue;
    }

    var val = where[p];
    // eslint-disable-next-line no-undefined
    if (val === null || val === undefined) {
      continue;
    }
    // Check there is an operator
    var operator = null;
    var exp = val;
