How to use helm commands in jenkins pipeline script

[admin]

I have been trying to deploy the image built on jenkins by docker to helm charts, i have referred couple of documents on website <a href="https://dev.to/sword-health/seamless-ci-cd-with-jenkins-helm-and-kubernetes-5e00" rel="nofollow noreferrer">https://dev.to/sword-health/seamless-ci-cd-with-jenkins-helm-and-kubernetes-5e00</a>
and <a href="https://cloudcompilerr.wordpress.co...kubernetes-run-jenkins-on-kubernetes-cluster/" rel="nofollow noreferrer">https://cloudcompilerr.wordpress.co...kubernetes-run-jenkins-on-kubernetes-cluster/</a> and managed till the point where docker image gets pushed into dockerhub but i get stuck at helm
i'm not getting what the error exactly is.
