Try updating source in script to inline. see this: qbox.io/blog/… — Praneeth

I recently bumped into this, but my solution was a little different.

I believe the ElasticSearch documentation here concerning scripting with reindex might be incorrect, or at least it did not work for me.

Instead of using source in the following:

"script": {
    "source": "if (ctx._source.foo == 'bar') {ctx._version++; ctx._source.remove('foo')}",
    "lang": "painless"
  }

I had to use inline:

"script": {
    "inline": "if (ctx._source.foo == 'bar') {ctx._version++; ctx._source.remove('foo')}",
    "lang": "painless"
  }

And then, worked like a charm. Checked with raw HTTP requests and python ElasticSearch client. This was on ElasticSearch version 5.5.1.
