Error while deploying kubeless function to kubernetes cluster by using serverless framework

I am trying to deploy a kubeless function using serverless. I created a kubernetes cluster using minikube and I am trying to follow this link following which

1. I installed serverless
2. created a template kubeless-nodejs
3. installed plugins with npm install
4. and tried to deploy using serverless deploy -v

but I am getting an error

/home/vin/serverless/kube/services/email/node_modules/serverless-kubeless/lib/config.js:56
  return JSON.parse(this.configMag.data[key]);
                                       ^
TypeError: Cannot read property 'runtime-images' of undefined
    at Config.get (/home/vin/serverless/kube/services/email/node_modules/serverless-kubeless/lib/config.js:56:44)

Please point me in the right direction

I found the issue. I had to deploy kubeless to the Kubernetes cluster I had to do this for that:

$ export RELEASE=$(curl -s https://api.github.com/repos/kubeless/kubeless/releases/latest | grep tag_name | cut -d '"' -f 4)
$ kubectl create ns kubeless
$ kubectl create -f https://github.com/kubeless/kubeless/releases/download/$RELEASE/kubeless-$RELEASE.yaml
