Error: create: failed to create: Secret "sh.helm.release.v1.my-release.v1" is invalid: 
data: Too long: must have at most 1048576 bytes

Helm stores release state in a Kubernetes object, and Kubernetes objects have a hard 1 MiB size limit. If your chart grows large (hello, “monster CRDs”), you can end up in a situation where helm install/upgrade fails even though nothing is “wrong” with your Kubernetes cluster.
