Lazy is throwing the following fatal error on pages where the preprocessor is run, on an item that is not an (Media) Entity Reference.
Call to a member function getValue() on null in lazy_preprocess_field
Enable the module and create a field with Lazy Loading enabled.
Now enter a SVG in that field, that is saved as an URL instead of a Media Item/Reference
We should check if the `#item` key in the preprocessor is available.
If not, we can assume that no target_id is available, so we can skip the processing.
Add an extra condition before using any #item values, like in the patch.
Not all content is available!
It's likely this issue predates Contrib.social: some issue and comment data are missing.
Patch #7 works but it doesn't fix the initial problem. The problem appears when you are trying to lazy load SVGs. This can work if the SVGs are wrapped in an <img> tag, but with this patch, they will simply be ignored. It's better to use $element['#items'] to load the file ID, which is the same even when we have ['#markup'] instead of the expected render array for files.
