hi @piyush_khandelw 

it seems there is no check for empty data in `getAttributeText()` function

try to get values of only your custom attributes with check of empty data and get its values from sources by calling below code instead of `$product->getAttributeText($var); `
`$product->getResource()->getAttribute($var)->getSource()->getOptionText(
$this->getData($product->getData($var)));`

I solve this using 

$attributes = $_product->getAttributes();
foreach ($attributes as $attribute) {
$var = $attribute->getAttributeCode();
$_product->offsetExists($var);

}

where offsetExist() check that attribute have value or not it return boolean value.
Thank you @shikha1193  for your reply.
