this is my config.json
```
{
"apiVersion": "v1",
"kind": "ConfigMap",
"metadata": {
"name": "corredor-config",
"namespace": "default"
},
"data": {
"CORREDOR_LISTENER": "0.0.0.0:80",
"CORREDOR_ENV": "prod",
"CORREDOR_LOG_ENABLED": "true",
"CORREDOR_LOG_LEVEL": "debug",
"CORREDOR_LOG_PRETTY": "true"
}
}
```

this is my index.js file
```
const Client = require('kubernetes-client').Client
const { KubeConfig } = require('kubernetes-client')
const kubeconfig = new KubeConfig()
kubeconfig.loadFromFile('/home/software/.kube/config')
const Request = require('kubernetes-client/backends/request')

const backend = new Request({ kubeconfig })
const client = new Client({ backend, version: '1.13' })

async function main() {
const namespaces = await client.api.v1.namespaces.get()
// ------------- Config -------------
// create corredor
const configCorredor = require('./config/corredor.json')
create = await client.apis.apps.v1.namespaces('default').configmaps.post({ body: configCorredor }).catch((err)=>{
console.log("Corredor Config err:", err);
});
}
main()
```

this is the error
```

please help me

Start with index.js and the client API path used for the ConfigMap request; compare that path with the kubernetes-client API structure and the Kubernetes version shown in the issue. Check config/corredor.json as the request body. Done means the request reaches a defined client resource and posts the ConfigMap without the undefined-property error.
