The scenario is when user tried do the payment and it failed due to payment gateway issue in that case order fall in to the failed order, Now I want to manually change the status of the order from fail to processing but when I try to do so I get this error.

Temporary I have add this solution but not sure if it will perfect and not affect other areas

public static function exclude_giveaway_from_other_discounts( $valid, $product, $coupon, $values ) {

        /*
        // disabled this code
        if ( self::is_a_free_item( $values ) && 0 >= $values['data']->get_price() ) {
               return false;
        }
        */

        // Added this code
	if ( self::is_a_free_item( $values ) 
		&& isset( $values['data'] ) 
		&& is_object( $values['data'] ) 
		&& method_exists( $values['data'], 'get_price' ) 
		&& 0 >= $values['data']->get_price() ) {			
		return false;
	}

	if ( self::is_bogo( $coupon->get_id() ) ) {
		return true;
	}

	return $valid;
}
