Error while uploading multiple images for a product in Laravel

Time:11-30

Im receiving this error, "foreach() argument must be of type array|object, null given" but with a successful upload, how can resolve it.

foreach ($this->attribute_values as $key=>$attribute_value) {
    $avalues = explode(",", $attribute_value);
    foreach ($avalues as $avalue) {
        $attr_value = new AttributeValue();
        $attr_value->product_attribute_id = $key;
        $attr_value->value = $avalue;
        $attr_value->product_id = $product->id;
        $attr_value->save();
    }
}

Well I wrapped the code in an if statement like this.

 if (is_array($this->attribute_values)){
            foreach ($this->attribute_values as $key => $attribute_value) {
                $avalues = explode(",", $attribute_value);
                foreach ($avalues as $avalue) {
                    $attr_value = new AttributeValue();
                    $attr_value->product_attribute_id = $key;
                    $attr_value->value = $avalue;
                    $attr_value->product_id = $product->id;
                    $attr_value->save();
                }
            }
    }
