monitoring-kube-prometheus-stack invalid chart reference

[freebased]

What happened? I tried to install kube-prometheus stack as described in FluxCD Guide. I got error like:

$ flux get helmreleases --all-namespaces
NAMESPACE       NAME                    REVISION        SUSPENDED       READY   MESSAGE                                                      
                                                                                                                                             monitoring      kube-prometheus-stack   41.7.4          False           False   HelmChart 'monitoring/monitoring-kube-prometheus-stack' is no

Helm repositories looks fine:

$ flux get sources helm --all-namespaces
NAMESPACE       NAME                    REVISION                                                                SUSPENDED       READY   MESSAGE

but here's the problem:

$ flux get sources chart --all-namespaces
