READMEs getting 404 on Helm Hub

[wallyqs]

Right now in the nats helm charts on helm hub I'm getting a 404 on the readmes from the NATS charts:

https://hub.helm.sh/charts/nats/nats

I had fixed it already at some point but somehow broke again readme should be there: https://github.com/nats-io/k8s/tree/master/helm/charts/nats

and in the command line it works too:

$ helm show readme nats/nats | head -n 1
# NATS Server

Any pointers on what to look at to fix it?

Thanks!

@wallyqs This looks to be a bug. I can manually extract the archive and see the readme. The error logs are reporting...

gzip: invalid header"

What process are you using to create the archive file and on which os?

Additionally, the Artifact Hub is a place you can list nats. In your case I would create an organization and then add the chart repository to the organization. I wonder how it would display there.

Thanks @mattfarina this is the output of helm version on OSX:

version.BuildInfo{Version:"v3.2.3", GitCommit:"8f832046e258e2cb800894579b1b3b50c2d83492", GitTreeState:"clean", GoVersion:"go1.13.12"}

I generate the tarball by calling helm package as I think it is regularly done, like:

git clone https://github.com/nats-io/k8s/
cd k8s/helm/charts/
helm package nats

# Then when releasing
helm repo index .

I'm seeing the same behavior for all of the charts that I host on helm hub as well. I was about to ping you in slack @mattfarina but found this issue first.

In my case, the charts are being packaged with the helm chart-releaser-action via GitHub actions.

Picking one as an example, https://hub.helm.sh/charts/billimek/speedtest-prometheus, shows 404s from the helm hub API. The chart lives here and the associated index.yaml for that chart is,

  speedtest-prometheus:

I'm trying to compare other charts which seem to render properly with those that don't and haven't yet seen a pattern.

[billimek]

FWIW, the same chart appears to render properly in the new Artifact Hub: https://artifacthub.io/packages/chart/billimek-charts/speedtest-prometheus

[wallyqs]

Interesting, the Helm charts for NATS also seem ok in artifacthub: https://artifacthub.io/packages/helm/nats/nats

[mattfarina]

This is likely an issue that was in Helm that has been fixed. The helm version that was being used by the Helm Hub was older due to #212. We no longer have that issue as this is turned down so I am closing.
