The fix is tested on staging and deployed to production.

After the fix is enrolled, the following query yields 1804 results:

curl -XPOST "http://172.18.0.3:9200/_all/_search?pretty=true" -H 'Content-Type: application/json' -d'
{
  "query": {
    "regexp": {
      "userId": {
        "value": "U.{32}"
      }
    }
  }
}'

Let's observe if the number stopps increasing after the fix.

Update: The number of documents w/ U.{32} userId stops at 1,804, so the API patch is successful 🎉

The indexes that needs to be migrated:

• articles: 296 documents
  • articles.references
• replyrequests: 499 documents
• articlereplyfeedbacks: 1009 documents

No documents in other index need migration.
