Adding additional logging to ExprMissingValue exception

[FreCap]

Issue #, if available:

In a simple GROUP BY queries I'm getting the following exception and need more info about the problem:

{
  "error": {
    "reason": "There was internal problem at backend",
    "details": "invalid value operation on MISSING_VALUE",
    "type": "IllegalStateException"
  },
  "status": 500
}

FAILS

POST _opendistro/_sql
{
  "query": "select ABC.Status, count(*) from my_index group by ABC.Status"
}

WORKS with ?format=json

POST _opendistro/_sql?format=json
{
  "query": "select ABC.Status, count(*) from my_index group by ABC.Status"
}
