You can replace null values to empty by below code in java-script

var remove_empty = function ( target ) {
  Object.keys( target ).map( function ( key ) {
    if ( target[ key ] instanceof Object ) {
      if ( ! Object.keys( target[ key ] ).length && typeof target[ key ].getMonth !== 'function') {
        target[ key ] = "";
      }
      else {
        remove_empty( target[ key ] );
      }
    }
    else if ( target[ key ] === null ) {
       target[ key ] = "";
    }
  } );
  return target;
};
