ArgoCD app-selector is not working

Hi! I configure my component yaml to use argocd/app-selector: app=${app_name} annotation but the plugin returns 404.

If I set the argocd/app-name: testapp annotation it works perfectly, but when I set argocd/app-selector: "app=testapp" it fails. The requests that the frontend is doing to the proxy is a GET to https://myargo.com/api/argocd/argocd/api/applications?selector=app%3Dtestapp.

Expected Behavior

Shows the list of apps that has the label app=testapp (the same list that I can see if I filter the apps in my ArgoCD by the same label)

Current Behavior

It shows the error: Error occurred while fetching data. Error: failed to fetch data, status 404: Not Found

Steps to Reproduce

• Set the label app=testapp to your argocd application manifest
• Add the argocd/app-selector: "app=testapp" annotation to your component’s config

Possible Solution

I think that there is a difference between the proxy endpoint that Backstage is using when you set the argocd/app-name annotation and the endpoint that is using when you set the app-selector (api/argocd/argocd/api/applications?selector=app%3Dtestapp)

Context

We cannot see the apps that we want to show in our component’s page
