I have used the same scenario on your server it's working but after migration these not working.t

We are experiencing the same situation with configurable a simple products in the cart, Magento is trying to fetch getConfigurableAttributeCollection() on a simple product;

PHP Fatal error: Uncaught Error: Call to undefined method Magento\Catalog\Model\Product\Type\Simple::getConfigurableAttributeCollection()

Did you find anything useful @ankit-root ?

[pixiemediaweb]

Figured out a the solution for our issue with simple products;

First extend;

Magento\Catalog\Model\Product\Type\Simple

Add function;
public function getConfigurableAttributeCollection(\Magento\Catalog\Model\Product $product) { return false; }

Then extend;

Magento\ConfigurableProduct\Helper\Product\Options\Loader

Rewrite the function load() and replace this part;

$attributeCollection = $typeInstance->getConfigurableAttributeCollection($product);
$this->extensionAttributesJoinProcessor->process($attributeCollection);

With;

$attributeCollection = $typeInstance->getConfigurableAttributeCollection($product); // this now returns false if this is a simple product

if($attributeCollection) {
$this->extensionAttributesJoinProcessor->process($attributeCollection);
} else {
$attributeCollection = array();
}
...

I found temporary solution adding simple condition in Magento\ConfigurableProduct\Helper\Product\Options\Loader::load(ProductInterface $product) after line no : 51

if (get_class($typeInstance) == 'Magento\Catalog\Model\Product\Type\Simple' || get_class($typeInstance) == 'Magento\Bundle\Model\Product\Type') 
{
            return null;
}

This is still a problem.

Just an update, I have a breakpoint set in Loader.php (magento-configurable-product\Helper\Product\Options\Loader.php) on line 52. At this breakpoint, the following things are true:

$product->getTypeId it is equal to "configurable"
$product->getTypeInstance() is equal to type "Magento\Catalog\Model\Product\Type\Simple.

I'm debugging to see if somehow i've managed to set this value, but its doubtful.

[MichaelThessel]

I'm seeing the same issue. In my case I get the error when searching for a sku using the keyword search field in the product grid in admin.

I will re-open this ticket as this is still being reported by multiple people and the proposed workarounds are just masking the problem.

@mitcht Did you get any results?

[antondkv]

The reason for the issue is using a deprecated load method for models.
You should use API Repository for loading the products.

To reproduce needs to inject Product model (not factory) to the constructor

[hostep]

I just saw this same error being thrown on a Magento 2.3.1 shop, having some particular products in your cart: bundled product + a configurable one. At the moment when you moved from the checkout to an external payment provider, a HTTP 500 error was thrown and we could see the error mentioned in this ticket in the error log on the server.

It turned out to get fixed by updating that Payment provider's module to the latest version.
More concretely, we were using https://github.com/MultiSafepay/Magento2Msp/releases version 1.7.1. By upgrading to 1.10.0 the issue got fixed.

So in this case, it was probably some incorrect code in the Payment provider module which caused the bug and might not have been a Magento core bug, but I can't say that with full confidence though.

Maybe this comment helps for other people who run into this and who are also using the MultiSafepay payment module.

On production following code works:
File: vendor\magento\module-configurable-product\Helper\Product\Options\Loader.php
Add below code after line # 51

if (strstr(get_class($typeInstance), 'Magento\Catalog\Model\Product\Type\Simple') !== false || strstr(get_class($typeInstance), 'Magento\Bundle\Model\Product\Type') !== false) {
    return null;
}

Check your custom modules or extensions and find if you are using either of the following -:

Magento\Catalog\Model\Product (in the constructor)

$this->_product->load($id)

or

$this->_objectManager->get('\Magento\Catalog\Model\Product')->load($id)

If yes then change it to use \Magento\Catalog\Api\ProductRepositoryInterface and load product using getById($id) instead. Hope it helps
