Unable to install remote charts using virtual helm repo in Jfrog Artifactory

I have created a Helm repository in Jfrog Artifactory using 'Quick Setup'.

Then used the Jfrog helm binary to add the virtual 'helm' repo: enter image description here

I am able to add custom charts to the virtual repo, install them but not able to install charts from the helm-remote (i.e stable) repo:

When I try to access any such chart, helm throws as error:

enter image description here

On the Artifactory web ui, the helm virtual repo lists all the remote charts, but I'm unable to install them:

I have done "helm repo update" multiple times. And also have deleted ~/.helm folder and "init" again. Still, am plagued by the same problem.

I see the following error in the Artifactory System Logs repeated several times:

2018-02-28 09:18:34,266 [art-exec-2] [ERROR] (o.a.a.h.r.m.HelmVirtualMerger:194) - 
Couldn't read index file in remote repository helm-remote : 
(was com.github.zafarkhaja.semver.UnexpectedCharacterException) 
(through reference chain: org.jfrog.repomd.helm.model.HelmIndexYamlMetadata["entries"]->java.util.LinkedHashMap["grafana"]->java.util.TreeSet[3])

enter image description here

What can be the possible issues here? Thank you for your help.

tl;dr - This issue was fixed in Artifactory 5.9.0 - https://www.jfrog.com/jira/browse/RTFACT-15668

The problem is that Artifactory didn't support Helm charts with non-SemVer 2 in version 5.8, and only after version 5.8 came out a non SemVer2 was added to the stable chart repo. (grafana 0.6) This issue was fixed in 5.9.0, and you should be able to resolve remote chart correctly.
