How to Display the Complete Description of a Helm Revision in Kubernetes

When working with Helm in Kubernetes, you may run into situations where an upgrade fails, leaving you puzzled with only a snippet of the error message. This can be especially frustrating if you need details about what went wrong in order to rectify the issue. Understanding how to view the complete description of a Helm revision is crucial for troubleshooting these types of errors effectively.
