为提高效率，请提供以下信息，问题描述清晰能够更快得到解决：
【 TiDB 使用环境】
按照官网的 TiDB 数据库快速上手指南 部署的单节点Linux集群做测试
【概述】 场景 + 问题概述
【备份和数据迁移策略逻辑】
csv文件是从google cloud 的bigquery导出来的，格式如下：
[root@iZwz9bg08mzvex3rn5k06wZ ~]# more csv/test.tokens.csv

【背景】 做过哪些操作
有试过用tidb-lightning.toml配置文件的方式，还是提示一样的错误
配置如下：
[lightning]
# 日志
level = "info"
file = "tidb-lightning.log"
[tikv-importer]
# 选择使用的 local 后端
backend = "local"
# 设置排序的键值对的临时存放地址，目标路径需要是一个空目录
sorted-kv-dir = "/tidb-data/sorted-kv-dir/"
[mydumper]
no-schema = true
data-source-dir = /nfs_storage/tmp/csv/
[mydumper.csv]
# 字段分隔符，必须为 ASCII 字符。
separator = ','
# 引用定界符，可以为 ASCII 字符或空字符。
delimiter = '"'
# CSV 文件是否包含表头。
# 如果为 true，首行将会被跳过。
header = true
# CSV 是否包含 NULL。
# 如果为 true，CSV 文件的任何列都不能解析为 NULL。
not-null = false
# 如果 `not-null` 为 false（即 CSV 可以包含 NULL），
# 为以下值的字段将会被解析为 NULL。
null = '\N'
# 是否解析字段内的反斜线转义符。
backslash-escape = true
# 是否移除以分隔符结束的行。
trim-last-separator = false
[tidb]
# 目标集群的信息
host = "192.168.11.105"
port = 4000
user = "root"
password = ""
# 表架构信息在从 TiDB 的“状态端口”获取。
status-port = 10080
# 集群 pd 的地址
pd-addr = "192.168.11.105:2379"

- 使用配置文件的方式执行：

Verbose debug logs will be written to tidb-lightning.log

报的错跟用命令行一样。
