[v2.go:105] write tcp 192.168.65.1:57934->192.168.65.4:8443: write: protocol wrong type for socket

Problem

We can copy a file to a pod using a command issued from a terminal

kubectl | oc cp ./target/ocp-fmp-build-install-1.0-exec.jar sb1-app-1-rxpc9:/deployments

that works fine but when we try to achieve the same thing using the client-go and remotecommand v2.go, then that fails with this error

E0907 06:53:18.293590   34159 v2.go:105] write tcp 192.168.65.1:57934->192.168.65.4:8443: write: protocol wrong type for socket
I0907 06:53:18.293718   34159 root.go:157] Error:
unable push files to pod: error while streaming command: Internal error occurred: error executing command in container: read unix @->/var/run/docker.sock: read: connection reset by peer

Why do we get protocol wrong type for socket ? Is there a workaround ?

The issue was related to the fact that it was not possible to store the file under the path defined /opt/app-root/src as src was a file and not a directory.
