Although configuring multiple helm charts (manifests) on a native helm service is supported as per https://developer.harness.io/docs/continuous-delivery/deploy-srv-diff-platforms/helm/native-helm-quickstart/#using-multiple-helm-charts-in-a-single-harness-service , During the execution a primary manifest has to be selected. This might benefit if the charts are different for different environments. manifestConfigurations: primaryManifestRef: <+input> However, deploying multiple helm charts when deploying a service isn't possible (The error NativeHelm deployment support only one manifest of one of types: HelmChart is noticed if the above block is removed). For instance, deploying a monitoring stack that contains multiple tools such as prometheus, grafana etc will require separate charts for the tools to be deployed. This request is for having an option to deploy all the charts from the manifest in the same service(monitoring stack) instead of having the charts deploy through separate services.
