@dhavisdjgm7fa4 

are you using php -7.2? if yes might be this plugin not compatible with php 7.2.

Reason why it's happening, in php7.2 count on null throws warning, see https://www.php.net/manual/en/migration72.incompatible.php

Hi @dhavisdjgm7fa4 

To resolve According to expcetion "1 exception(s):Exception #0 (Exception): Notice: Undefined index: media_gallery".

For better practice you can try to use Magento2 Service Layer. You can save a new image using \Magento\Catalog\Api\ProductAttributeMediaGalleryManagementInterface::create

Under the method the attribute "media_gallery" will be set and then \Magento\Catalog\Api\ProductRepositoryInterface::save will be invoked. And inside of this method the method \Magento\Catalog\Model\Product\Gallery\Processor::addImage will be invoked, which basically invoked, when you run addImageToMediaGallery.

It may help you to resolve issue.
