不可序列化异常包装器 (not_serializable_exception_wrapper) 错误排查与解决

# 错误响应包含被包装的异常信息
{
  "error": {
    "type": "not_serializable_exception_wrapper",
    "reason": "actual_exception_name: actual error message",
    "caused_by": {
      "type": "...",
      "reason": "..."
    }
  }
}

# 启用详细错误追踪
GET /_search?error_trace=true&pretty=true

# 在客户端查看完整的异常堆栈

# 在远程节点上查看实际异常
grep -i "error\|exception" /path/to/easysearch/logs/easysearch.log | tail -100

# 查找特定的错误
grep -A 10 "actual_exception_name" /path/to/easysearch/logs/easysearch.log

# 包装的异常才是实际需要解决的问题
# 根据 exception.name 确定实际错误类型
# 然后按照该特定错误的修复方法处理
