   {
    "role": "user", 
    "content": "List two data science professions with related skills in json format."
   }

连接错误

通常由用户端或服务端的连接问题引起

例：InternalServerError、APIConnectionError、APITimeoutError

可能的解决方案：
- 检查连接配置
- 若无效，联系技术支持

资源限制错误

通常由于请求频率或文本长度受限

例：ConflictError、RateLimitError

可能的解决方案：
- 检查限额与限制
- 确保请求在限额内
