ZlibError: zlib: unexpected end of file for cp.cpFromPod method

[bodycombathuang]

when I use cp.cpFromPod for a file with size about 6MB, I get error
c:\typescript\node_modules\minizlib\index.js:154
this[_onError](new ZlibError(err))

I suspect that the network connection is getting interrupted, can you try to reproduce this locally with a minikube cluster where network isn't a problem?

There's also this PR that may help:

#1396

[bodycombathuang]

hi @brendandburns 1396 does not provide any workaround or solution
if the file size is small, (several bytes), I cannot reproduce, it is reproduced for file that is larger than 5MB each time

https://github.com/kubernetes-client/javascript/blob/master/src/cp.ts
async ({ status }) => { writerStream.close(); if (status === 'Failure' || errStream.size()) { throw new Error(Error from cpFromPod - details: \n ${errStream.getContentsAsString()}); } await tar.x({ file: tmpFileName, cwd: tgtPath, }); },

i guess it is because tar.x command is executed before "tar zcf" command is finished
