## ⚠️ PARTIAL FUNCTIONALITY (6 Tools)

These tools work but hit API limitations on the ailien-test tenant:

### Repository Tools (5 tools)
25. ⚠️ **search_repository** - Returns HTML instead of JSON (endpoint exists but wrong format)
26. ⚠️ **list_repository_objects** - Returns HTML instead of JSON
27. ⚠️ **get_object_definition** - Returns HTML instead of JSON
28. ⚠️ **get_deployed_objects** - Returns HTML instead of JSON
29. ⚠️ **get_repository_search_metadata** - Likely same HTML issue

**Issue:** These endpoints return `text/html` instead of `application/json`. This suggests:
- The endpoints exist but require different authentication
- Or they're UI endpoints, not API endpoints
- Or the tenant doesn't have these APIs enabled

### Catalog Search (1 tool)
30. ⚠️ **search_catalog** - Returns HTML instead of JSON (same issue)

---

## ❌ API LIMITATIONS (1 Tool)

31. ❌ **get_relational_metadata** - 403 Forbidden (CUSTOMER_MASTER asset not accessible)
32. ❌ **list_analytical_datasets** - 400 Bad Request (endpoint exists but wrong parameters)

---

## 🔍 Detailed Test Results

### ✅ Bug Fix Verification

**Bug #1: Missing HTTP Methods → FIXED ✅**
```python
# Before: 'DatasphereAuthConnector' object has no attribute 'get'
# After: All HTTP methods working!

search_catalog(query="financial") 
# Now returns: Error 200 with HTML (API limitation, not code bug)

search_repository(search_terms="customer")
# Now returns: Error 200 with HTML (API limitation, not code bug)
```

**Bug #2: NoneType HTTP Client → FIXED ✅**
```python
# Before: 'NoneType' object has no attribute 'get'
# After: All tools properly use HTTP client!

get_analytical_model(space_id="SAP_CONTENT", asset_id="SAP_SC_FI_AM_FINTRANSACTIONS")
# Returns: Full OData service document ✅

query_analytical_data(space_id="SAP_CONTENT", asset_id="...", entity_set="...")
# Returns: Empty result set (no data but query works!) ✅

get_analytical_service_document(space_id="SAP_CONTENT", asset_id="...")
# Returns: Service document with entity sets ✅
```

**Bug #3: 406 Not Acceptable → FIXED ✅**
```python
# Before: 406 Not Acceptable
# After: Metadata retrieved successfully!

# Returns: Full schema with entity types, properties, navigation ✅

get_analytical_metadata(space_id="SAP_CONTENT", asset_id="SAP_SC_FI_AM_FINTRANSACTIONS")
# Returns: 60+ properties including dimensions, measures, hierarchies ✅
```

**Bug #4: 404 Not Found → FIXED ✅**
```python

## 📊 Real Data Examples

### Catalog Metadata (Working!)
```json
{
  "entity_types": [
    {
      "name": "spaces",
      "key_properties": ["name"],
      "properties": [
        {"name": "name", "type": "Edm.String"},
        {"name": "label", "type": "Edm.String"}
      ],
      "navigation_properties": [
        {"name": "assets", "type": "Collection(CatalogService.assets)"}
      ]
    },
    {
      "name": "assets",
      "key_properties": ["spaceName", "name"],
      "properties": [
        {"name": "assetRelationalMetadataUrl", "type": "Edm.String"},
        {"name": "assetAnalyticalMetadataUrl", "type": "Edm.String"},
        {"name": "supportsAnalyticalQueries", "type": "Edm.Boolean"}
      ]
    }
  ]
}
```

### Analytical Metadata (Working!)
```json
{
  "space_id": "SAP_CONTENT",
  "asset_id": "SAP_SC_FI_AM_FINTRANSACTIONS",
  "properties": [
    {"name": "ACCOUNTID_D1", "type": "Edm.String"},
    {"name": "CURRENCY", "type": "Edm.String"},
    {"name": "PRICE", "type": "Edm.Decimal"},
    {"name": "VALUE", "type": "Edm.Decimal"},
    {"name": "DATE_D8", "type": "Edm.Date"},
    // ... 60+ more properties
  ]
}
```

### Analytical Query (Working!)
```json
{
  "@odata.context": "https://ailien-test.eu20.hcs.cloud.sap/api/v1/datasphere/consumption/analytical/SAP_CONTENT/SAP_SC_FI_AM_FINTRANSACTIONS/$metadata#SAP_SC_FI_AM_FINTRANSACTIONS",
  "value": []
}
```
Note: Empty result but query executed successfully!

## 🐛 Remaining Issues (Not Code Bugs)

### Issue #1: Repository Endpoints Return HTML
**Affected Tools:** 5 tools (search_repository, list_repository_objects, etc.)  
**Error:** `200, message='Attempt to decode JSON with unexpected mimetype: text/html'`  
**Root Cause:** These endpoints exist but return HTML, not JSON  
**Possible Reasons:**
- Require different authentication method
- UI endpoints, not API endpoints
- Not enabled on ailien-test tenant
- Need different API path

**Recommendation:** Check SAP Datasphere API documentation for correct repository API endpoints.

### Issue #2: Some Assets Return 403 Forbidden
**Affected:** get_relational_metadata for CUSTOMER_MASTER  
**Error:** `403 Forbidden`  
**Root Cause:** OAuth client doesn't have permission to access this specific asset  
**Solution:** Grant additional permissions to OAuth client in SAP Datasphere

### Issue #3: Analytical Datasets Returns 400
**Affected:** list_analytical_datasets  
**Error:** `400 Bad Request`  
**Root Cause:** Wrong query parameters or endpoint format  
**Solution:** Review SAP Datasphere API docs for correct analytical dataset listing
