do keep in mind that this kind of message is almost never an error.
It's simply a warning that you wouldn't even see w/o -w. All that it
means is that a scalar with an undefined value is being evaluated to
a string (which results, by default, in an empty string).
Is the build failing or halting at this point for you?
That said, it's indeed a good to point those out, as someone either
should have initialized a scalar when it wasn't, or that someone was
expecting the scalar to always have a value, and so the absence of it
may indicate an unexpected condition resulting from an error elsewhere.
