# CRITICAL: Composer Rendering Engine Investigation
**Task ID**: CRITICAL-COMPOSER-ENGINE-001
**Status**: URGENT EXECUTION REQUIRED
**Priority**: CRITICAL
**Owner**: Claude Code
**Created**: 2025-07-03 20:20 EST
**Dependencies**: Browser diagnostic completed
---
## 🚨 **ROOT CAUSE IDENTIFIED**
**User Investigation Results:**
- ✅ Browser shows Composer interface correctly
- ✅ URL navigation works (valid composition ID)
- ❌ **ALL compositions show blank content** (not just ours)
- ❌ **All compositions titled "Sem título"** (titles not saving/displaying)
- ❌ **Universal rendering failure** across all compositions
## 🎯 **CRITICAL DISCOVERY**
**This is NOT an automation or API interception issue.**
**This is a fundamental Composer application rendering problem** affecting all compositions.
## 🔍 **IMMEDIATE INVESTIGATION REQUIRED**
### **Check 1: Composer Application State**
```javascript
// Check if Composer app is fully loaded
await page.evaluate(() => {
console.log('🔍 APP CHECK: Window objects');
console.log('Vue:', typeof window.Vue);
console.log('React:', typeof window.React);
console.log('jQuery:', typeof window.$);
console.log('App router:', typeof window.$router);
console.log('App store:', typeof window.$store);
});
```
### **Check 2: JavaScript Errors**
```javascript
// Monitor for JavaScript errors that might break rendering
page.on('pageerror', error => {
console.log('🚨 PAGE ERROR:', error.message);
});
page.on('error', error => {
console.log('🚨 BROWSER ERROR:', error.message);
});
```
### **Check 3: Resource Loading**
```javascript
// Check if all necessary assets loaded
await page.evaluate(() => {
const scripts = document.querySelectorAll('script');
const stylesheets = document.querySelectorAll('link[rel="stylesheet"]');
console.log('🔍 RESOURCES: Scripts loaded:', scripts.length);
console.log('🔍 RESOURCES: Stylesheets loaded:', stylesheets.length);
// Check for failed resources
const images = document.querySelectorAll('img');
const failed = Array.from(images).filter(img => !img.complete || img.naturalHeight === 0);
console.log('🔍 RESOURCES: Failed images:', failed.length);
});
```
### **Check 4: API Configuration**
```javascript
// Check if Composer has correct API endpoints configured
await page.evaluate(() => {
console.log('🔍 CONFIG: Window config objects');
console.log('Config:', window.config);
console.log('API_URL:', window.API_URL);
console.log('BASE_URL:', window.BASE_URL);
// Check localStorage for config
const configs = Object.keys(localStorage).filter(key =>
key.includes('config') || key.includes('api') || key.includes('url')
);
console.log('🔍 CONFIG: LocalStorage configs:', configs);
});
```
## 🎯 **LIKELY CAUSES**
### **Cause A: Missing JavaScript Dependencies**
- Composer app not fully loading
- Missing Vue/React components
- Broken JavaScript bundles
### **Cause B: API Configuration Issue**
- Composer can't connect to backend
- Wrong API endpoints configured
- Authentication/CORS issues
### **Cause C: Environment Configuration**
- Development vs. Production mode issue
- Missing environment variables
- Database connection problems
### **Cause D: Asset Loading Failure**
- CDN resources not loading
- Network connectivity issues
- Resource path problems
## ✅ **SUCCESS CRITERIA**
1. **Identify why Composer cannot render ANY compositions**
2. **Fix the fundamental rendering issue**
3. **Verify that existing compositions become visible**
4. **Confirm our automated compositions then work**
## 🚀 **EXPECTED OUTCOME**
Once the Composer rendering engine is fixed:
- All existing "Sem título" compositions should display properly
- Our automation-created compositions should become visible
- API interception won't be needed (normal flow will work)
---
**This changes everything - fix Composer rendering first, then our automation will work!**
