helm direcotry charts not exist
The issue is as follow: you must not extract your intern chart to
charts folder under the umbrella,
the umbrella chartws folder meant to be empty and used only by the helm dependency build command
umbrella
charts // this folder must be empty and manged and populated only by "helm dependency build %umbrelal_name%"
temp-charts
|_ // put here you extracted chart (was .tgz ...)
tempalte
|_
Chart.yaml // point to chart in temp-charts not in charts
valeus.yaml
