The original condition if (type === 'text' || type === '2dsphere') on line 546 still includes the old 'text' check, but this code path is now unreachable since 'text (full text search)' is handled above. The condition should be updated to only check for '2dsphere' or the old 'text' condition should be removed entirely.
