Overriding model file is not working in Magento 2.2.5

I tried to override model, but it is not working. I need to override:

MagentoCatalogModelProductAttributeBackendPrice to
PawanCatalogModelRewriteProductAttributeBackendPrice

But it not working.

My di.xml path Pawan/Catalog/etc/di.xml:

di.xml

Pawan/Catalog/etc/di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="MagentoCatalogModelProductAttributeBackendPrice" typr="PawanCatalogModelRewriteProductAttributeBackendPrice" />
</config>

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="MagentoCatalogModelProductAttributeBackendPrice" typr="PawanCatalogModelRewriteProductAttributeBackendPrice" />
</config>

My model file:

<?php
namespace PawanCatalogModelRewriteProductAttributeBackend;

class Price extends MagentoCatalogModelProductAttributeBackendPrice

public function afterSave($object)

$writer = new ZendLogWriterStream(BP . '/var/log/importmissingorders.log');
$logger = new ZendLogLogger();
$logger->addWriter($writer);
$logger->info("custom model");

/** @var $attribute MagentoCatalogModelResourceModelEavAttribute */
$attribute = $this->getAttribute();
$attributeCode = $attribute->getAttributeCode();
$value = $object->getData($attributeCode);

// $value may be passed as null to unset the attribute
if ($value === null



It is still executing the core file only.

What am I doing wrong?

di.xml

Pawan/Catalog/etc/di.xml

Change typr,

typr

<preference for="MagentoCatalogModelProductAttributeBackendPrice" typr="PawanCatalogModelRewriteProductAttributeBackendPrice" />


to type:

type

<preference for="MagentoCatalogModelProductAttributeBackendPrice" type="PawanCatalogModelRewriteProductAttributeBackendPrice" />
