## 🐛 Runtime Errors Fixed
### Error #1: Item Not Found (Language Variants)
**Status:** ✅ ALREADY WORKING (v1.4.0 smart defaults)
- Smart language defaults implemented
- Templates always queried with `language='en'`
- Enhanced error messages with language hints
### Error #2: Field Not Found
**Status:** ✅ ALREADY WORKING
- Correct `field() { name value }` subselection already implemented
- Test validates proper GraphQL syntax
### Error #3: Template Not Found
**Status:** ✅ FIXED
- **Issue:** Templates weren't forced to `language='en'`
- **Fix:** Force `language='en'` for all template queries
- **Change:** Enhanced error messages with language requirement hint
- **File:** `src/sitecore-service.ts` - `getTemplate()` method
### Error #4: getTemplates Schema Mismatch
**Status:** ✅ FIXED (CRITICAL SCHEMA FIX)
- **Issue 1:** Used non-existent `templates()` query
- **Issue 2:** Tried to query `path` field on `ItemTemplate` (only has `id` and `name`)
- **Fix 1:** Use `item().children()` instead of non-existent `templates()` query
- **Fix 2:** Remove `path` field access from ItemTemplate
- **Schema Rule:** `ItemTemplate` only has `{ id, name }` per introspectionSchema.json
- **File:** `src/sitecore-service.ts` - `getTemplates()` method
### Error #5: getChildren Schema Mismatch
**Status:** ✅ ALREADY WORKING (FALSE POSITIVE)
- Implementation correctly uses direct array access
- No `.results` field usage
- Test validates proper structure
---
## 📋 Schema Validation Rules
### ItemTemplate Type Structure
```typescript
// FROM: src/sitecore-types.ts (generated from introspectionSchema.json)
export interface ItemTemplate {
id: ID; // ✅ EXISTS
name: string; // ✅ EXISTS
// path: string; // ❌ DOES NOT EXIST - WILL CAUSE ERROR!
}
```
### Query Patterns (Schema-Validated)
| Need | ✅ Correct Query | ❌ Incorrect Query |
|------|------------------|-------------------|
| Templates | `item(path: "/sitecore/templates/...").children()` | `templates()` (doesn't exist) |
| Single Field | `item().field(name: "X") { name value }` | `item().field(name: "X")` (missing subselection) |
| Children | `item().children(first: 100)` | `item().children.results` |
| ItemTemplate fields | `template { id name }` | `template { id name path }` |

## ⚠️ CRITICAL REQUIREMENTS (Breaking Changes)
### 1. Smart Language Defaults
**PRODUCTION RULE:**
```typescript
// Templates, renderings, system items: ALTIJD 'en'
if (path.startsWith('/sitecore/templates')) language = 'en';
if (path.startsWith('/sitecore/layout')) language = 'en';
if (path.startsWith('/sitecore/system')) language = 'en';
// Content items: 'en' als default, tenzij expliciet opgegeven
if (path.startsWith('/sitecore/content')) language = language || 'en';
```
**WAAROM:**
- ✅ Templates en renderings zijn ALTIJD in 'en' (Sitecore standaard)
- ✅ Content kan meertalig zijn
- ✅ Voorkomt "item not found" errors bij verkeerde language
### 2. Helix Architecture Awareness
**PRODUCTIE STRUCTUUR:**
```
/sitecore/templates/
├── Foundation/ # Basis templates (altijd 'en')
├── Feature/ # Feature templates (altijd 'en')
└── Project/ # Project-specifieke templates (altijd 'en')
/sitecore/layout/
├── Renderings/
│ ├── Foundation/
│ ├── Feature/
│ └── Project/
└── Layouts/
```
**CRITICAL:**
- ✅ Alle templates MOETEN in 'en' language
- ✅ Content volgt site language settings
- ✅ Renderings zijn in 'en'
- ✅ Media Library vaak in 'en'
### 3. Version Management
**ALTIJD GEBRUIKEN:**
- ✅ Gebruik laatste versie tenzij expliciet anders gevraagd
- ✅ Response MOET altijd `versionCount` bevatten
- ✅ Format: `{ version: 2, versionCount: 5 }` = "versie 2 van 5"
### 4. Field Discovery via Template
**WANNEER GEVRAAGD naar "fields van item X":**
1. Gebruik `sitecore_get_item_fields` (NIET individuele field queries!)
2. Dit haalt ALLE fields op basis van template
3. Includes inherited fields (Helix base templates)
4. Returns: `{ totalFields: 42, fields: [{name, value}] }`
### 5. GraphQL Schema Correctness
**CRITICAL SCHEMA FIXES:**
```graphql
# ✅ CORRECT: Search returns results.items
search(keyword: "Home") {
results {
items { # PLURAL: items, not item!
id
name
}
}
}
# ✅ CORRECT: DateField/TextField require { value }
... on Statistics {
created { value } # NOT just: created
createdBy { value } # NOT just: createdBy
}
```

## 🔄 Migration Guide
### From v1.3.0 to v1.4.0
**Breaking Changes:**
1. **Search Queries** - Access via `results.items` instead of `results`:
```typescript
// ❌ v1.3.0:
const items = result.search.results;
// ✅ v1.4.0:
const items = result.search.results.items;
```
2. **Language Parameter** - Nu optional overal:
```typescript
// ✅ v1.3.0:
getItem(path, language = "en")
// ✅ v1.4.0:
getItem(path, language?) // Smart defaults!
```
**Backward Compatibility:**
- ✅ Default language 'en' blijft werken
- ✅ Bestaande code werkt (maar gebruikt nu smart defaults)
- ✅ Search code moet update naar `.results.items`
