There's always a frame, even in batch sessions.  Observe:

  emacs -batch --eval "(message \"%s\" (selected-frame))"
    => #<frame F1 017b9d08>

It's just that it's not a frame which this feature could use.

You could explicitly test for non-interactive sessions, and skip the
test, or display a message that this test can only be run
interactively.  Would that be good enough?
