Cannot filtering on bytes data type

[xiangfu0]

Table schema:

{
  "metricFieldSpecs": [
  ],
  "dimensionFieldSpecs": [
    {
      "dataType": "BYTES",
      "name": "uuid"
    },

      "timeType": "MILLISECONDS",
      "name": "start_time_millis"
    }
  },
  "schemaName": "myTable"
}

Sample query:

select * from myTable where uuid = "c8b3bce0b378fc5ce8067fc271a34892" limit 10

The assertion assert rawValue instanceof byte[]; at line 35, file: org.apache.pinot.core.realtime.impl.dictionary.BytesOnHeapMutableDictionary will pass for String object.
