Hi @Ashish_k_php 

To resolve it just re create the attribute which causes this error, in the backend but do not enable for layered navigation or search. 

It may help you to resolve issue.
Thank you.

Hi @Ashish_k_php 

Please search file by below path in M1:

app/code/core/Mage/Catalog/Model/Layer/Filter/Abstract.php

There must be below function:

// \Mage_Catalog_Model_Layer_Filter_Abstract::getAttributeModel
public function getAttributeModel()
{
    $attribute = $this->getData('attribute_model');
    if (is_null($attribute)) {
        Mage::throwException(Mage::helper('catalog')->__('The attribute model is not defined'));
    }
    return $attribute;
}

In this function you can create logs for attribute.

Hi @Ashish_k_php , 

Please follow below steps to figure out the attribute code which is causing error.

1. Search for the attributes in the attributes grid using filter on grid through Use In Search.

2. After you get the list, check for the attributes in the database that whether we have added any model with those attributes. 

3. Later at the end, try to disable attributes for search one by one which have any model's and hope we will get our culprit attribute which is causing issue.

Thanks!

@Nishu Jindal  thank you for your reply.

We filter the for search in the admin side and check that attribute on the database but not any attribute have attribute_model set.

Please guide me if you have any other solution.

Hi @Ashish_k_php ,

Can you please add below lines in the index.php

ini_set('display_errors', 1);

ini_set('display_startup_errors', 1);

error_reporting(E_ALL);

After that try to reproduce the error and check the log entries in [Magento_Root]/var/log/

Thanks!
