It seems there are edge cases where some static functions in class-linkbacks-mf2-handler.php return null after failing all the conditionals. Other methods call these but fail to test for null. This leads to some instances of fatal errors. This push works for my site and stops the errors. It may be that better defaults can be found and/or more helpful actions in case of a wrong var type.
