no chart version found - semver range issue

[psolarcz]

Version: ghcr.io/fluxcd/source-controller:v0.15.4

I'm getting an error: no chart version found for XXX-09.20.x:

flux get all -A

However it exist in our private repo:

helm search repo XXX --version "09.20.x"
NAME                        CHART VERSION   APP VERSION DESCRIPTION
XXX-helm-repo-dev/XXX       09.20.22        09.20.22    XXX Helm Charts

It's also present in the index.yaml file:

cat data/helmrepository/flux-system/XXX-helm-repo-dev/index.yaml
apiVersion: v1
entries:
  XXX:

  - apiVersion: v2

    version: 09.20.22

When I specify version explicitly it works fine, I have problem only when I use some range operator or wildcards.

Edit:

I found source of a problem - our version was incorrect - 09.20.22 should not have leading 0.

This was returning an error:

Version segment starts with 0

Not sure if this is expected behaviour that there is no error, for sure it makes troubleshooting more difficult :)

@psolarcz I believe that's because 09.20.22 is not a valid semver: https://regex101.com/r/vkijKf/1/

Found your issue while also playing around with chart's dev version. #205 and #410 were a big help for me, I think something like this will work: 0.0.0-09-20-22

Hi We are encountering somewhat similar issues on HelmRepository, but this time with larger numbers. It seems something like 3.1008.240831 is accepted but 3.1008.2409008 is not. I tried looking into the code to see if there is any truncation, but could not find it. Semver code seems to parse each of the 3 elements as uint64. Any hint would be appreciated.
