Remote error from mongot :: caused by :: Index 12 out of bounds for length 12

MongoDB Atlas Atlas Search

Hi,
While using Atlas Search feature on M2 cluster I’ve got error Remote error from mongot :: caused by :: Index 12 out of bounds for length 12

This is not working query:

db.getCollection('my-documents').aggregate([
  {
    "$search": {
      "compound": {
        "filter": [
          {
            "equals": {
              "value": ObjectId('5ea6fa18ef17e8002708feea'),
              "path": "tenantId"
            }
          }
        ],
        "must": [
          {
            "text": {
              "query": "Abcd",
              "path": [
                "field1",
                "field2",
                "field3"
              ],
              "fuzzy": {
                "prefixLength": 2
              }
            }
          }
        ]
      },
      "highlight": {
        "path": [
          "field1",
          "field2",
          "field3"
        ]
      }
    }
  },
  {
    "$limit": 15
  },
  {
    "$project": {
      "_id": 1,
      "field1": 1,
      "field2": 1,
      "field3": 1,
      "score": {
        "$meta": "searchScore"
      },
      "highlight": {
        "$meta": "searchHighlights"
      }
    }
  }
])

After few experiments I realised that it will work when I remove “filter” operator or “highlight” option from $search but then I will lose key logic.
What is interesting on M0 tire clusters I don’t have this problem. I’m not sure if it is cluster tire related error or data related error.

Thanks for any help.

Hi @Jakub_Zloczewski,

Is it happen for the same index?

Can you share index desc and sample document?

Have you tried rebuilding the index (drop + create)

Best

@Pavel_Duchovny
I rather would not share data and index.
Is there any way someone will look at my cluster?

Yes, it is happen for the same index.
I’ve tried rebuilding the index few times and nothing changed.
