Templating [namespace] Error updating options: e.replace is not a function

Hi All,
Please I need advice on fixing these errors.
I’m noticing these errors in grafana dashboard when importing these jason files (source # flux2/manifests/monitoring/monitoring-config/dashboards at main · fluxcd/flux2 · GitHub)

Template variable service failed e.replace is not a function
Templating [namespace]

Error updating options: parse error at char 1: vector selector must contain label matchers or metric name

Grafana version is

  • Grafana v7.3.7 (1e261642f4)


welcome to the :grafana: forum, @reppakayala

those json files imported without error for me. I was using Grafana 8.5.5

Thank you @mattabrams.
Actually, I am facing this issue and due to the reason, it’s not working.

Any idea/ hint to fix this issue, please?

Helm upgrade failed: failed to create resource: Internal error occurred: failed calling webhook “prometheusrulemutate.monitoring.coreos.com”: Post “https://prometheus-kube-prometheus-operator.metrics.svc:443/admission-prometheusrules/mutate?timeout=10s”: no endpoints available for service “prometheus-kube-prometheus-operator”

All these issues are fixed.

The grafana dashboards were working fine not sure suddenly stopped working.

How do troubleshoot it to find out the root cause?.

what @yosiasz said. also try increasing the verbosity of the Grafana server logs to debug and note any errors. For printing to console, set the console logs to debug as well.
