I upgraded my site from EE 1.14.1.0 to 1.14.3.10 and now when I navigate to a configurable product that uses a drop down (not swatches) to change the image, the image does not change.

I have looked at the solutions in these exchanges, but none of them solved my issue:

Configurable products: product image not updating after selecting attribute in dropdown

^ This solution while it technically solves my problem, it doesn't keep the options in a dropdown, but switches them to swatches. We want the options to remain in a dropdown.

https://stackoverflow.com/questions/41845427/typeerror-product-configurableswatches-is-not-a-constructor-in-magento-1-9-3

^ This solution solves a JS error I also got, but doesn't fix the images switching part.

As soon as I navigate to the page, these errors are generated in system.log:

ERR (3): Warning: array_merge_recursive() expects at least 1 parameter, 0 given in /app/code/core/Mage/ConfigurableSwatches/Helper/Productimg.php on line 336
ERR (3): Warning: array_unique() expects parameter 1 to be array, null given in /app/code/core/Mage/ConfigurableSwatches/Helper/Productimg.php on line 337

ERR (3): Warning: in_array() expects parameter 2 to be array, null given in /app/code/core/Mage/ConfigurableSwatches/Helper/Productimg.php on line 345

Could this be what is causing the issue? If so, what might a solution be?

This was not an issue prior to updating. I have a support ticket out with Magento, but they are taking their sweet time (since November), so I thought I would see if anyone has any solutions.

Update 3/12

Magento sent me a patch that resolved the errors in system.log, but I am still unable to swap images based on the option selected in the dropdown.

In app/code/core/Mage/ConfigurableSwatches/Helper/Productimg.php update the filterImageInGallery function as follows:

public function filterImageInGallery($product, $image)

 if (!Mage::helper('configurableswatches')->isEnabled()) 
 return true;
 

 if (!isset($this->_productImageFilters[$product->getId()])
 && $childAttributeLabelMapping = $product->getChildAttributeLabelMapping()
 ) 
 $mapping = call_user_func_array("array_merge_recursive", $childAttributeLabelMapping);
 $filters = array_unique($mapping['labels']);
 $filters = array_merge($filters, array_map(function ($label) 
 return $label . Mage_ConfigurableSwatches_Helper_Productimg::SWATCH_LABEL_SUFFIX;
 , $filters));
 $this->_productImageFilters[$product->getId()] = $filters;

 return !in_array(Mage_ConfigurableSwatches_Helper_Data::normalizeKey($image->getLabel()),
 $this->_productImageFilters[$product->getId()]);
 

 return true;
