helm proxy issues

[sabhavivek]

Brief description about the issue we are facing,

We use Nexus 3.74
We use helm proxy for bitnami charts,
URL: https://charts.bitnami.com/bitnami
index.yaml having wrong urls.
Expected values in index.yaml
urls:
- keycloak-22.2.1.tgz

What we are getting,
urls:
- keycloak-24.2.2.2
Due to this, we could not update and facing errors.

Following some components having this issue(around 150 wrong URLs),

• flux-2.3.1.1
• ghost-22.0.4.4
• ghost-22.0.3.3
  Etc.

Instead of giving urls with tgz , we are getting below,
urls:
- keycloak-24.2.3.3

Reproduced above in local desktop:
Tried this in a test setup, same behaviour when configuring helm proxy with bitnami in nexus. Tried earlier nexus version too.(3.72)
Index.yaml having same values as previous version.

Same behaviour observed in latest version too - 3.75

Same issue when pull any helmchart from bitnami with version oss 3.68.1-02. Anyone help?
Error: failed to fetch 502 Bad Gateway

Bitnami repository switched to OCI in recent charts, workaround using docker proxy is described here #201 (comment)
