How to fix .GeneratorURL?

[Nazargora]

Hi everyone, thank you for your work. I have an issue. I have this *<{{ .GeneratorURL }}|Check>* in my alertmanager.yml and it is one of my rule` rules:

• alert: 'Target Down'
  expr: up == 0
  labels:
  severity: critical
  for: 3m
  annotations:
  summary: "Target {{ $labels.instance }} is down"
  description: "Target unavailable. Job: {{ $labels.job }}"
  And one week ago all worked well and when I click on my Check I go into Grafana Explore. But now when I click on my Check I guess I have double encoding URLhttps://example/explore?orgId=1&left=%5B%22now-1h%22,%22now%22,%22VictoriaMetrics%22,%7B%22expr%22:%2522up+%253D%253D+0%2522`. Someone can explain me how I can fix it because I have this error Could not parse Explore URL The requested URL contains invalid parameters, a default Explore state has been loaded. An unexpected error happened SyntaxError: Invalid regular expression: invalid group specifier name Please help me 😩
