I need error log details in JSON structure.

Approach:
1. Task: Create error log in JSON
2. Complexity: complex - 8-10 fields, 3-4 levels
3. Format rules: proper braces/brackets, quoted keys, correct value types
4. Structure: Organize data logically with appropriate nesting
5. Populate fields with realistic example data based on the schema.

Output:
{
  "error_id": "04fc9fc0-d7ed-4a22-ad0d-a2c11cc5fbd0",
  "timestamp": "2026-01-06T09:43:32.507568",
  "level": "CRITICAL",
  "service": "conditionService",
  "message": "Myself standard late treatment rule.",
  "stack_trace": [
    "at knowledge.py:423",
    "at expect.py:191"
  ],
  "context": {
    "user_id": "dc933ca4-1b99-4133-b2f1-d6ffa34ca7c6",
    "request_id": "080929c4-3fbd-40eb-bc2f-bba8e6be8243"
  }
