Issue: grep -R checks failing silently, causing build to fail Solution: Replace grep with simple [ -f ] and [ -d ] checks Changes: - Added set -e for immediate failure on errors - Removed complex grep -R checks (unreliable) - Use simple file existence checks instead: [ -f dist/index.html ] [ -d dist/assets ] [ -f wwwroot/index.html ] - Better error messages for debugging - Fixed rm -rf to not fail if directory missing This ensures CI/CD step fails explicitly with clear error message rather than silently failing on grep.
