Hi,

I'm unable to apply sql query on one index and i get this error,

```auto
{
  "error": {
    "root_cause": [
      {
        "type": "unsupported_operation_exception",
        "reason": null
      }
    ],
    "type": "unsupported_operation_exception",
    "reason": null
  },
  "status": 500
}

```

However, i can run sql queries on other indexes i have and it works perfectly fine. I'm not sure why one specific index is not working.

Any advice please?

Thanks,  
Sunitha

@sunitha.eswaraiah are there any `flattened` field types in that index?  
Would be useful to know the query that fails and, also, the full stack trace from logs.

A wild guess that it's about this PR: [https://github.com/elastic/elasticsearch/pull/50823](https://github.com/elastic/elasticsearch/pull/50823) but before knowing for sure, I need answers to above questions. Thanks.

Hi @Andrei_Stefan

Thanks for the solution. I had `search_as_you_type` datatype in the mapping.  
I reindexed removing the `search_as_you_type` and i'm able to apply SQL on the index.

Thanks you 🙂 👍
