Helm diff release “Error: unknown flag: --template”

[rahulwagh]

I was trying to use helm plugin diff but when I was trying to find the diff between the release it is throwing me an error

Here is my helm diff command

helm diff release myhelloworld myhelloworld2

Error: unknown flag: --template

Error: plugin "diff" exited with error

Here are my releases

helm list -a

NAME         	NAMESPACE	REVISION
myhelloworld 	default  	3       
myhelloworld2	default  	1       

Is there anything wrong with my helm diff command ?

Just as a first glance, it seems like in the function:
func getChart(release, namespace string) (string, error) {
args := []string{"get", release, "--template", "{{.Release.Chart.Name}}"}

seems to be missing "all" or some other {command}
so perhaps
args := []string{"get", "all", release, "--template", "{{.Release.Chart.Name}}"}

I'm having the exact same issue with Helm v3.4.2. helm diff version just shows HEAD.
Any idea on if this will get fixed any time soon?

Error: exit status 1: Error: unknown flag: --template
