Rancher 2.x can't read Artifactory helm repos

Rancher 2.x
1

Have spent days trying to track down the issue, but it looks like even with proper credentials, Rancher 2.x’s Add Catalog feature does not like the YAML index spit out by Artifactory. (This repo works with the helm cli tools)

I get the following response from Rancher:

Error while parsing response from [https://XXXHOST_REDACTEDXXX/artifactory/rosetta-helm-virtual/index.yaml/index.yaml], error: yaml: line 9: did not find expected <document start>

Is it because of a missing — preamble?
