The issue post is not accurate as the helm command was in the form:

`helm push MY-chart-1.0.0-oci.tgz oci://my-jfrog-artifactory/my-oci-helm --username *** --password ***`

Based on the regular expression mentioned in https://github.com/helm/helm/issues/12055#issuecomment-1536999256:

name MUST match the following regular expression:
[a-z0-9]+([._-][a-z0-9]+)*(/[a-z0-9]+([._-][a-z0-9]+)*)*
reference as a tag MUST be at most 128 characters in length and MUST match the following regular expression:
[a-zA-Z0-9_][a-zA-Z0-9._-]{0,127}

with oci the chart name must be lowercase.
