# SOLUTION: CI Failures After v1.7.4 Hotfix Release
Date: 2025-09-12 11:00 AM
Status: ✅ VERIFIED ISSUES IDENTIFIED
Verification: All three failures confirmed with evidence
Problem Category: CI/CD Release Process
## Problem Statement
Three CI checks are failing on the main branch after the v1.7.4 hotfix release:
1. GitHub Packages publishing - 409 Conflict error
2. NPM release - Version mismatch error
3. Cross-Platform Simple (Windows) - Performance test flakiness
## Environment Context
- Platform: GitHub Actions CI
- Branch: main
- Tag: v1.7.4
- Key Variables:
- GITHUB_TOKEN: present
- NPM_TOKEN: present (but unused due to earlier failure)
- Package.json version: 1.7.3 (not updated)
## Prerequisites
- [ ] Access to repository settings for tokens
- [ ] Permission to update package.json
- [ ] Understanding of GitFlow workflow
## Working Solutions
### Issue 1: GitHub Packages Publishing Failure
**Error**: `409 Conflict - Cannot publish over existing version`
**Root Cause**: Version 1.7.4 already exists in GitHub Packages from a previous successful publish
**Solution**:
```bash
# Option 1: Skip if already published (modify workflow)
# In .github/workflows/publish-github-packages.yml, add:
- name: Check if version exists
id: check_version
run: |
VERSION=$(node -p "require('./package.json').version")
if npm view @DollhouseMCP/mcp-server@$VERSION version --registry=https://npm.pkg.github.com 2>/dev/null; then
echo "exists=true" >> $GITHUB_OUTPUT
else
echo "exists=false" >> $GITHUB_OUTPUT
fi
- name: Publish to GitHub Packages
if: steps.check_version.outputs.exists != 'true'
run: npm publish
```
### Issue 2: NPM Release Failure
**Error**: `Tag version (1.7.4) doesn't match package.json version (1.7.3)`
**Root Cause**: The hotfix workflow didn't update package.json before creating the tag
**Solution**:
```bash
# Fix for current state - Update package.json on main
git checkout main
npm version 1.7.4 --no-git-tag-version
git add package.json package-lock.json
git commit -m "chore: Update version to 1.7.4 to match tag"
git push
# Prevention - Update hotfix workflow to bump version
# In hotfix creation process, add:
npm version patch # or specific version
git add package.json package-lock.json
git commit -m "chore: Bump version for hotfix"
```
### Issue 3: Windows ToolCache Performance Test Flakiness
**Error**: Test expects <50ms but got 54ms
**Location**: `test/__tests__/unit/utils/ToolCache.test.ts:213`
**Solution**:
```typescript
// In test/__tests__/unit/utils/ToolCache.test.ts
// Line 208-213, update the threshold:
// BEFORE:
const performanceThreshold = process.env.CI ? 50 : 10;
// AFTER - More lenient for Windows CI:
const performanceThreshold = process.env.CI
? (process.platform === 'win32' ? 100 : 50) // 100ms for Windows CI
: 10; // 10ms for local
// Alternative - Skip performance assertions in CI:
if (!process.env.CI) {
expect(duration).toBeLessThan(performanceThreshold);
}
```
## Verification Steps
```bash
# Verify GitHub Packages issue
gh workflow run publish-github-packages.yml --ref main
# Verify NPM release after package.json fix
git pull
node -p "require('./package.json').version" # Should show 1.7.4
# Verify ToolCache test locally
npm test -- test/__tests__/unit/utils/ToolCache.test.ts
```
## Common Failures (DO NOT DO THESE)
- ❌ **Don't delete and republish packages**: This breaks existing installations
- ❌ **Don't force push to main**: This violates GitFlow
- ❌ **Don't disable tests**: Performance tests catch real issues
- ❌ **Don't ignore version mismatches**: They cause deployment failures
## Debug Notes
- Initial hypothesis: NPM_TOKEN was missing (from session notes)
- Actual cause: Version mismatch prevented NPM publish from even attempting
- Key insight: Hotfix workflow needs version bump automation
## Action Plan
### Immediate Fixes (Priority Order):
1. **Fix package.json version** (5 minutes)
```bash
git checkout main
npm version 1.7.4 --no-git-tag-version
git add package.json package-lock.json
git commit -m "chore: Update version to 1.7.4 to match tag"
git push
```
2. **Fix ToolCache test threshold** (10 minutes)
- Create PR to update threshold for Windows CI
- Set to 100ms for Windows, 50ms for others
3. **Update GitHub Packages workflow** (15 minutes)
- Add version existence check
- Skip publish if already exists
### Long-term Improvements:
1. **Automate version bumping in hotfix workflow**
2. **Add pre-tag version validation**
3. **Consider using semantic-release for automation**
4. **Add retry logic for flaky performance tests**
