How to reproduce:

Preconditions: Helm and Prometheus are installed into the cluster

Steps:

helm install --name promviz ./helm/promviz
helm install --name promviz-front ./helm/promviz-front

Wait for the pods to be ready
kubectl port-forward promviz-front-promviz-front-6bd8c9578f-88488 -n default 8080:8080
Open localhost:8080 in the browser

Expected result: promviz dashboard with data
Current result: promviz dashboard stuck on loading. Error message in js console is:

Found the solution:
You should give promviz address in configuration instead of promviz-front.

@Cristian04 Did you found the solution for this?
I'm having the same error here.

Thanks @Istalacar.
I found now. You need place the the url of promviz in helm/promviz-front/values.yaml:
Like this:

env:
  updateURL: "http://localhost:9091/graph"

@rodrigopandini I've tried your approach and it didn't work, still unable to connect:

Did you encounter this error too? Thanks!
