That looks like a nonsense change, assigning a variable to itself... Instead of adding the appropriate null check.

In summary, the issue is that we are trimming null values.

Also, I would say we need a better query to identify the classes used in the apex recipes package because I think at the moment it is using the ***@***.***' *text in the class body to identify the classes related to the package. I have comment helper extension vs code which adds @group to every class so it is picking all the non-apex receipe related classes and therefore we are seeing this null.
