In my article content type, I've added a header image (field_header_image) field which I placed a default image into it so that all articles would have a default image used if one wasn't needed. However, when creating an article and leaving that field as the default value, it doesn't actually use that default value. The page is created as if that value is empty.
Is there any way to make sure that this default value is used?
Is there a way to do this through the .theme file? Is this the best way to do it?
