Gutenberg default initial values for FocalPointPicker

Question

Ok, I found the solution by myself. Inside withSelect it is needed to assign default value if getEditedPostAttribute is empty.

// Helper function to check if received meta object is empty or not
function isEmpty(obj) {
  for(var key in obj) {
      if(obj.hasOwnProperty(key))
          return false;
  }
  return true;
}

PhotoControl = withSelect(
  (select) => {
      let myFocal = select('core/editor').getEditedPostAttribute('meta')['focalPoint'];
      if(isEmpty(myFocal)) { focal={ "x": 0.5, "y": 0.5 }; } // Solution is here. If is empty object assign default values.
      return {
          img: select('core/editor').getEditedPostAttribute('meta')['img'],
          focalPoint: myFocal
      }
  }
)(PhotoControl);
