helm proxy repo fails when processing index.yaml due to colon in url

[emileonhardt]

What problem are you trying to solve?

I am proxying the bitnami helm chart repo (https://charts.bitnami.com/bitnami) for local access.
When I try to use the proxied repo with "helm repo add", this does not work:

Error: looks like "https://xxx/repository/helm-bitnami-proxy/" is not a valid chart repository or cannot be reached: empty index.yaml file

The downloaded index.yaml ist empty. In the Nexus log, I see the following stack trace:

Do you have a workaround you are using at present?

No.

What feature or behavior is this required for?

Helm Proxy Repo.

How could we solve this issue? (Not knowing is okay!)

Supporting URLs with Colons in them.

Tell us about your Nexus Repository deployment: what version, operating system, and database are you using?

OSS 3.69.0-02 on a Windows VM with OrientDB.

Anything else?

This worked until a couple of days ago. I am attaching the offending index.yaml as a zip file.
index.zip

This issue is also affecting us as well. It appears to only be happening on our Bitnami helm proxy, which was working fine previously. Other helm proxies are still working ok.

Interestingly, our Bitnami proxy repo does have an index.yaml file in it with a file size of around 18mb but when browsing to it, a blank page is returned.
