secret creation error when passing additional certificate

[mmurhamm]

I need to pass a server cert (or cert chain?) to a scanner in order to prevent ssl error when connecting to local registry.
helm command:

helm upgrade --install --namespace aqua scanner aqua-helm/scanner --set platform=k3s,serviceAccount.create=true,serviceAccount.name=aqua-scanner-sa,imageCredentials.create=true,imageCredentials.username=<my_user>,imageCredentials.password=<my_pw>,server.scheme=https,server.serviceName=<my_tenant>.cloud.aquasec.com,server.port=443,scannerToken=<my_token>,directCC.enabled=false,additionalCerts[0].createSecret=true,additionalCerts[0].secretName="scanner-localreg-cert-chain",additionalCerts[0].certFile="localreg-pem.base64" --dry-run --debug

I get the following error:

install.go:222: [debug] Original chart version: ""
install.go:239: [debug] CHART PATH: C:\Users\<my_win-user>\AppData\Local\Temp\helm\repository\scanner-2022.4.8.tgz

Error: template: scanner/templates/scanner-cert-secret.yaml:11:20: executing "scanner/templates/scanner-cert-secret.yaml" at <.Release.Name>: nil pointer evaluating interface {}.Name
helm.go:84: [debug] template: scanner/templates/scanner-cert-secret.yaml:11:20: executing "scanner/templates/scanner-cert-secret.yaml" at <.Release.Name>: nil pointer evaluating interface {}.Name

The scanner installs okay w/o additionalCerts[] but then fails to connect to local registry (ping okay) because of not trusted server cert (verified using wget --spider to registry url from within scanner container).

What is the problem?
Thanks.
