Metrics Anomaly Chart rendering fails

Summary

Metrics Anomaly Chart rendering fails

Steps to reproduce

  1. Setup a devops project with metrics enabled

  2. Create a new custom dashboard with an anomaly chart

dashboard: 'Metrics Anomaly'
panel_groups:
  - group: 'Memory'
    panels:
      - title: "anomalies"
        type: anomaly-chart
        y_label: "MB"
        metrics:
          - id: anomaly_requests_normal
            query_range: 'avg(sum(container_memory_usage_bytes{container_name!="POD",pod_name=~"^%{ci_environment_slug}-([^c].*|c([^a]|a([^n]|n([^a]|a([^r]|r[^y])))).*|)-(.*)",namespace="%{kube_namespace}"}) by (job)) without (job) / count(avg(container_memory_usage_bytes{container_name!="POD",pod_name=~"^%{ci_environment_slug}-([^c].*|c([^a]|a([^n]|n([^a]|a([^r]|r[^y])))).*|)-(.*)",namespace="%{kube_namespace}"}) without (job)) /1024/1024'
            label: "memory_1024"
            unit: "MB"
          - id: anomaly_requests_normal_upper_limit
            query_range: 20
            label: "upper limit"
            unit: "MB"
          - id: anomaly_requests_normal_lower_limit
            query_range: 5
            label: "lower limit"
            unit: "MB"
