UnhandledPromiseRejection when running cp.cpToPod with wrong namespace/pod name

[pauloamed]

Describe the bug
Getting the following uncaght error when running cp.cpToPod with a wrong namespace or pod name.

Uncaught Error UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason "#<ErrorEvent>".

Traces down to connect(path, textHandler, binaryHandler) in WebSocketHandler, returning a 404 when trying to connect to the cluster+namespace+pod.

Client Version
0.18.1

Server Version
1.26.7

To Reproduce
Just run the following code using a wrong namespace or pod name

Expected behavior
Correct error handling by the cpToPod method.

Example Code

import * as k8s from '@kubernetes/client-node';

const kc = new k8s.KubeConfig();
kc.loadFromDefault();

const cp = new k8s.Cp(kc);


const main = async () => {
    try{
        await cp.cpToPod(NAMESPACE, , WRONG_POD_NAME, './test.txt', '/tmp');
    }catch(err) {
        console.log(err)
    }
};

main();

Environment (please complete the following information):

• OS: Ubuntu 22.04.2 LTS
• NodeJS Version: v16.19.0
• Cloud runtime: GKE

Additional context
I guess that the main problem is that there isn't an await here
