Undefined index: media_type while addImage to product

[ankursachdeva11]

Preconditions

1. Magento 2.2.1 CE

Steps to reproduce

1. Use Magento\Catalog\Model\Product\Gallery\Processor: addImage function to add an image to a product.

Expected result

1. Image should get added.

Actual result

1. Message: Notice: Undefined index: media_type in /vendor/magento/module-catalog/Model/Product.php on line 2554

We have tried to find the comparison between 2.2.1 and 2.2.2. We got this which is causing issue:
in addImage function:(media_type) is missing which is causing issue.

Please check.

In Addition to this,

if we use $product->addImageToMediaGallery(params); and then $product->save() function to add images.
still we are getting error: Message: Notice: Undefined index: media_type in /vendor/magento/module-catalog/Model/Product.php on line 2554
