[ResponseOps][Alerts] Stack alerts page crashes on certain local storage configurations

[cnasikas]

On certain local storage configurations, the alerts page in the Stack crashes. It is unknow how to reproduce these configurations from the UI.

Steps to reproduce

1. Go to DevTools and create the following rule. The rule will generate some alerts.

POST kbn:/api/alerting/rule
{
  "params": {
    "timeField": "@timestamp",
    "index": [
      ".kibana-event-log*"
    ],
    "esQuery": "{\n    \"query\":{\n      \"match_all\" : {}\n    }\n  }",
    "size": 100,
    "thresholdComparator": ">",
    "timeWindowSize": 10,
    "timeWindowUnit": "m",
    "threshold": [
      0
    ],
    "aggType": "count",
    "groupBy": "all",
    "termSize": 5,
    "searchType": "esQuery",
    "excludeHitsFromPreviousRun": false,
    "sourceFields": []
  },
  "consumer": "discover",
  "schedule": {
    "interval": "10s"
  },
  "tags": [],
  "name": "EQ rule with consumer: discover",
  "rule_type_id": ".es-query",
  "actions": []
}

2. Add the following snippet to the stackAlerts.default.pageFilters local storage property.

Local storage snippet

```javascript { "viewMode": "view", "id": "8f6e7415-e181-4f76-a1ca-7131fc8ca7de", "panels": { "0": { "type": "optionsListControl", "order": 0, "grow": true, "width": "small", "explicitInput": { "id": "0", "dataViewId": "unified-alerts-dv", "fieldName": "kibana.alert.status", "title": "Status", "hideExclude": true, "hideSort": true, "hidePanelTitles": true, "placeholder": "", "ignoreParentSettings": { "ignoreValidations": true }, "selectedOptions": [ "active" ], "hideActionBar": true, "persist": true, "hideExists": true, "existsSelected": false, "exclude": false } }, "1": { "type": "optionsListControl", "order": 1, "grow": true, "width": "small", "explicitInput": { "id": "1", "dataViewId": "unified-alerts-dv", "fieldName": "kibana.alert.rule.name", "title": "Rule", "hideExclude": true, "hideSort": true, "hidePanelTitles": true, "placeholder": "", "ignoreParentSettings": { "ignoreValidations": true }, "hideExists": true, "selectedOptions": [], "existsSelected": false, "exclude": false } }, "2": { "type": "optionsListControl", "order": 2, "grow": true, "width": "small", "explicitInput": { "id": "2", "dataViewId": "unified-alerts-dv", "fieldName": "kibana.alert.group.value", "title": "Group", "hideExclude": true, "hideSort": true, "hidePanelTitles": true, "placeholder": "", "ignoreParentSettings": { "ignoreValidations": true }, "selectedOptions": [], "existsSelected": false, "exclude": false } }, "3": { "type": "optionsListControl", "order": 3, "grow": true, "width": "small", "explicitInput": { "id": "3", "dataViewId": "unified-alerts-dv", "fieldName": "tags", "title": "Tags", "hideExclude": true, "hideSort": true, "hidePanelTitles": true, "placeholder": "", "ignoreParentSettings": { "ignoreValidations": true }, "selectedOptions": [], "existsSelected": false, "exclude": false } } }, "defaultControlWidth": "small", "defaultControlGrow": true, "controlStyle": "oneLine", "chainingSystem": "HIERARCHICAL", "showApplySelections": false, "ignoreParentSettings": { "ignoreFilters": false, "ignoreQuery": false, "ignoreTimerange": false, "ignoreValidations": false }, "filters": [ { "meta": { "index": "unified-alerts-dv", "key": "kibana.alert.status", "disabled": false }, "query": { "match_phrase": { "kibana.alert.status": "active" } } } ] } ```

3. Navigate to the Stack alerts page. It should crash.
