How to set up and validate locally

1. Run helm upgrade -f custom.values.yaml [RELEASE_NAME] for your cluster.

2. Generate a bad event in snowplow by sending an incorrect payload. Replace #{collector host} and #{appId} with your application's collector host and appId.

   POST /com.snowplowanalytics.snowplow/tp2 HTTP/1.1
   Host: #{collector host}
   accept: */*
   accept-language: en-GB,en-US;q=0.9,en;q=0.8
   content-type: application/json; charset=UTF-8
   origin: null

   sec-ch-ua-mobile: ?0
   sec-ch-ua-platform: "macOS"
   sec-fetch-dest: empty
   sec-fetch-mode: cors
   sec-fetch-site: cross-site

   x-gitlab-appid: #{appId}
   
   {
       "schema": "iglu:com.snowplowanalytics.snowplow/payload_data/jsonschema/1-0-4",
       "data": [
           {
               "e": "pv",
               "page": "Test Page",
               "eid": "any-string",
               "tv": "js-3.12.0",
               "tna": "gitlab",
               "aid": "#{appId}",
               "p": "web",
               "cs": "UTF-8",
               "lang": "en-GB",
               "res": "2560x1440"
           }
       ]
   }

3. Check clickhouse table default.snowplow_bad_events . schema should not have enriched payload, user id or ip address.
