namespacedApps not working

[jkleinlercher]

Expected Behavior

I use the feature apps-in-any-namespace in argocd and want to display such an app which is in a specific namespace. I followed the procedure "Support for apps in any namespace beta feature" in https://www.npmjs.com/package/@roadiehq/backstage-plugin-argo-cd

Current Behavior

I enable namespacedApps with this property:
https://github.com/suxess-it/sx-cnp-oss/blob/0fb9906442c3d102ba479a12d016a7dce80a9644/platform-apps/charts/backstage/values-uibklab.yaml#L106

then set argocd/app-namespace in the catalog-info.yaml:
https://github.com/suxess-it/team1-demo-app1/blob/ea0232050f234d60a73cecb1532b1c225085e02b/catalog-info.yaml#L8-L9

However, the app is not fetched. Instead a http 403 is returned. This is always the case when an app which is not in argocd should get loaded:

and in the backstage logs I see the request but without the query parameter "?appNamespace=adn-team1" . However, I don't know if the query parameters get logged anyways.

In argocd-server log I see that this request comes without the configure appNamespace. It requests the app in the default argocd namespace:

Steps to Reproduce

as describe above

Possible Solution

Context

Your Environment

"name": "@roadiehq/backstage-plugin-argo-cd",
"version": "2.6.5",

"name": "@roadiehq/backstage-plugin-argo-cd-backend",
"version": "3.0.2",

We just messed up with the new argocd plugin version. As we recognized the new argocd frontend plugin uses the argocd backend plugin and not the proxy api anymore. Is that true? Do we still need the proxy configuration or is every communication working via the argocd backend plugin?

        "/argocd/api":
          target: http://sx-argocd-server.argocd:80/api/v1/
          changeOrigin: true
          secure: false
