Common Questions Answered

Q: Do I need to read all 4 documents?

A: No. Use this as a guide:

• Must read: VALIDATION_CHECKLIST.md (to implement)
• Reference while working: JSON_EXAMPLES.md
• Background info: UPDATE_PLAN.md sections as needed
• Overview only: SUMMARY.md

Q: Which document has the complete corrected JSON?

A: JSON_EXAMPLES.md has full corrected workflows for all 4 files.

Q: Can I just copy/paste the JSON?

A: Yes! But review each file section to understand the changes:

1. Note what's different (connections added, ACL bug fixed)
2. Verify node names match your current file
3. Validate syntax after pasting

Q: How long will this take?

A:

• Understanding: 30 minutes
• Implementation: 90 minutes
• Validation: 30 minutes
• Commit: 15 minutes
• Total: 2.5-3 hours (relaxed pace with validation)

Q: What if validation fails?

A: See VALIDATION_CHECKLIST.md → "Troubleshooting" section. Most common issues are:

• Missing commas in connections
• Node name mismatches
• ACL bug not fixed

Q: Can I do Phase 2 (error handling)?

A: Yes, but it's optional. Focus on Phase 1 first (just connections).

Getting Unstuck

If you're confused...

1. Go to SUMMARY.md - Quick overview of the problem
2. Go to UPDATE_PLAN.md - Specific section about your issue
3. Go to JSON_EXAMPLES.md - See the actual code
4. Go to VALIDATION_CHECKLIST.md - Step-by-step instructions

If validation fails...

1. Check VALIDATION_CHECKLIST.md → "Troubleshooting"
2. Run syntax check: python3 -m json.tool file.json
3. Compare with JSON_EXAMPLES.md - is your JSON matching?
4. Review node names - do they match connections?

If you're stuck on the ACL bug...

1. Go to UPDATE_PLAN.md → "Issue #4: ACL Variable Reference Bug"
2. Find the exact line in fetch-data.json
3. Replace $build_filter with $steps.build_filter
4. Done!

Important: Before You Start

✅ Do:

• Read SUMMARY.md first (5 min)
• Use VALIDATION_CHECKLIST.md while implementing
• Reference JSON_EXAMPLES.md for correct syntax
• Test after each file
• Commit when complete

❌ Don't:

• Start without reading SUMMARY.md
• Copy JSON without understanding changes
• Skip validation
• Modify node logic or positions
• Forget to fix ACL bug in fetch-data.json

Quick Command Reference

# Validate syntax
python3 -m json.tool packages/data_table/workflow/sorting.json > /dev/null && echo "✅"

# Validate all 4 files
for file in packages/data_table/workflow/*.json; do
  python3 -m json.tool "$file" > /dev/null && echo "✅ $(basename $file)" || echo "❌ $(basename $file)"
done

# Show differences from original
diff packages/data_table/workflow/sorting.json.bak packages/data_table/workflow/sorting.json

# Create feature branch
git checkout -b fix/data-table-n8n-compliance

# Stage and commit
git add packages/data_table/workflow/*.json
git commit -m "fix(data_table): add n8n schema compliance"

# Push to remote
git push -u origin fix/data-table-n8n-compliance
