ChildProcessError: stdout maxBuffer length exceeded

We have the following code, which throws error after Kubernetes upgrade:

module.exports.getReplicationControllers = async function getReplicationControllers(namespace) {    const kubeConfig = (await getNamespacesByCluster()).get(namespace);    if (!kubeConfig) throw new Error(`No clusters contain the namespace ${namespace}`)    const kubeConfigEscaped = shellEscape([kubeConfig]);      const namespaceEscaped = shellEscape([namespace]);    const result = await cpp(`kubectl --kubeconfig ${kubeConfigEscaped} get replicationcontrollers -o json -n ${namespaceEscaped}`);    console.error(result.stderr);    /** @type  */    const resultParsed = JSON.parse(result.stdout);    const serviceNames = resultParsed.items.map((item) => item.metadata.name);    return serviceNames;  }  

ChildProcessError: stdout maxBuffer length exceeded kubectl --kubeconfig /kubeconfig-staging get replicationcontrollers -o json -n momentum-uat (exited with error code ERR_CHILD_PROCESS_STDIO_MAXBUFFER)

What I've tried so far is:

  const result = await cpp(`kubectl --kubeconfig ${kubeConfigEscaped} get replicationcontrollers -o=jsonpath='{.items[*].metadata.name}' -n ${namespaceEscaped}`);    console.error(result.stderr);    const serviceNames = result.split(' ');    return serviceNames;  

Which returns

TypeError: result.split is not a function

I am not super versed with JavaScript, any help appreciated.
