When I add a view.xml file to my theme I get the following error:
Exception #0 (Magento\Framework\View\Asset\File\NotFoundException): Unable to resolve the source file for 'frontend/Holy/mytheme/en_GB/Magento_Catalog/images/product/placeholder/.jpg' error message
I can fix it by uploading new product placeholder images on the Magento admin.
Is there another way to avoid this error? Why is this error occurring in the first place?
