TernaryFilter not working with date column?

                TernaryFilter::make('dob')
                    ->label('Date of Birth?')
                    ->trueLabel('Has Date of Birth')
                    ->falseLabel('Missing Date of Birth?')
                    ->queries(
                        true: fn (Builder $query): Builder => $query->whereNotNull('dob'),
                        false: fn (Builder $query): Builder => $query->whereNull('dob'),
                    )
                    ->nullable(),
