@alexmt I am not 100% sure if #16267 ever made its way into the release-2.9 branch either, which was to fix a very similar issue.

Do we also need that?

Hey @crenshaw-dev / @leoluz / @alexmt ... Friendly reminder that you have library/module consumers out there. Please be careful about changing function names and signatures... This is technically a breaking change - just got caught out by this when bumping versions on terraform-provider-argocd and the only mention of this in the release notes is a [chore](fix: cherry-pick fixed cli admin dashboard cmd) 😉
