Error: Array must contain values for all object properties

I have schema like below:

const MMSchema = {
  name: 'MM',
  primaryKey: 'art',
  properties: {
    art:  'int',
    tar: {type: 'string', optional: true},
    p_date: {type: 'string', optional: true},
    p_time: {type: 'string', optional: true},
    article: {type: 'string', optional: true},
    design_no: {type: 'string', optional: true},
    grp: {type: 'string', optional: true},
    color: {type: 'string', optional: true},
    composition: {type: 'string', optional: true},
    width: {type: 'int', optional: true},
    weight: {type: 'int', optional: true},
    barcode: {type: 'string', optional: true},
    drm: {type: 'string', optional: true},
    d_date: {type: 'string', optional: true},
    adet: {type: 'int', optional: true},
    c_adet: {type: 'int', optional: true},
    ey: {type: 'int', optional: true},
    gy: {type: 'int', optional: true},
    ys: {type: 'int', optional: true},
  }
};

sample input:

   }

It works:

realm.write(() => {
   realm.create('MM', response.mmArray[0], true);
});

It doesn’t work. error message: Array must contain values for all object properties

realm.write(() => {
   realm.create('MM', response.mmArray, true);
});;

How can I write batch ?

Just to be clear, your first example with response.mmArray[0] works alright but batch insertion does not? If so that is because we don’t yet support batch insertion. There is an issue for this here #242

Until we support this you could insert using a loop or one of the array iteration methods:

realm.write(() => {
   response.mmArray.forEach((values) => {
      realm.create('MM', values, true);
   });
});

Yes, Chrome debug mode was the issue. After disabling chrome debug mode, 20k items take ~2 seconds. Thanks !
