BarNumber is at Score-level.
#() is an (empty) vector in scheme. You need to tell LilyPond to
interpret this native _scheme_-expression. As usual prepend it with
another '#'. Makes for:
\override Score.BarNumber.break-visibility = ##(#f #t #t)

Alas, what you really want may be:
\set Score.barNumberVisibility = #first-bar-number-invisible-save-broken-bars
