-#### 2. Async Test Issues
+#### 2. TaskGroup/Infrastructure Errors
+
+**Symptom**: `RuntimeError: Essential taskgroup missing` or similar infrastructure errors
+
+**Solution**:
+```bash
+# Try the simple tests first - they don't require full TrustGraph infrastructure
+./run_simple_tests.sh
+
+# Or run specific simple test files
+pytest tests/unit/test_text_completion/test_vertexai_simple.py -v
+pytest tests/unit/test_text_completion/test_vertexai_core.py -v
+```
+
+**Why this happens**:
+- The full TrustGraph processors require async task groups and Pulsar infrastructure
+- The simple tests focus on testing the core logic without infrastructure dependencies
+- Use simple tests to verify the VertexAI logic works correctly
+
+#### 3. Async Test Issues
 ```python
 # Use IsolatedAsyncioTestCase for async tests
 class TestAsyncService(IsolatedAsyncioTestCase):
