We recently upgraded to 7.19.8 and our helm repo stopped functioning. We were able to trace the issue back to malformed Chart.yaml files in already existing charts, which caused indexing to fail, resulting in an empty index.yaml in the virtual repo.
Chart.yaml (note the trailing " on the version)
Index log error:
Ideally, Artifactory should be modified so that it either handles these special characters properly, or fails gracefully for individual chart errors so it can continue indexing the rest of them.
