Got error when filter with boolean field

[treecy]

select *
from new_summary_daily-2018.01.22
-- is_published is a boolean type field
where is_published=true 

When I running this query I got null_pointer_exception error.

But if I change to

...
where is_published= 'true' 

It works well.

I know Elastice search allows you to pass a JSON true, so for the previous case maybe could use the following JSON

{
  "query": {
    "term": {
      "is_published": true 
    }
  }
}

I'm not sure if this is not supported yet?

SELECT * FROM new_summary_daily-2018.01.22 WHERE is_published=TERM(true)

{
  "from": 0,
  "size": 200,
  "query": {
    "bool": {
      "filter": [
        {
          "bool": {
            "must": [
              {
                "term": {
                  "is_published": {
                    "value": true,
                    "boost": 1
                  }
                }
              }
            ],
            "adjust_pure_negative": true,
            "boost": 1
          }
        }
      ],
      "adjust_pure_negative": true,
      "boost": 1
    }
  }
}
