Unable to post in configmaps

I am working on minikube

this is the minikube start command log

* minikube 1.12.3 is available! Download it: https://github.com/kubernetes/minikube/releases/tag/v1.12.3
* To disable this notice, run: 'minikube config set WantUpdateNotification false'

* Preparing Kubernetes v1.17.3 on Docker 19.03.6 ...
* Launching Kubernetes ... 
* Enabling addons: default-storageclass, storage-provisioner
* Done! kubectl is now configured to use "minikube"

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
