我想从kubernetes pod复制文件到本地机器，但显示类似tihs的错误：

> kubectl cp texhub-server-service-6f8d688c77-kvhgg:"/app/core.21" /Users/xiaoqiangjiang/core.21
tar: removing leading '/' from member names
Dropping out copy after 0 retries
error: unexpected EOF

为什么会发生这样的事呢？我该怎么做才能解决这个问题？我已经尝试添加了retries参数，仍然面临这个问题：

> kubectl cp texhub-server-service-6f8d688c77-kvhgg:"/app/core.21" /Users/xiaoqiangjiang/core.21 --retries=3
tar: removing leading '/' from member names
Resuming copy at 888832 bytes, retry 0/3
tar: removing leading '/' from member names
Resuming copy at 1505280 bytes, retry 1/3
tar: removing leading '/' from member names
Resuming copy at 2125824 bytes, retry 2/3
tar: removing leading '/' from member names
Dropping out copy after 3 retries
error: unexpected EOF

这是pod列表：
