NullPointerException when streaming es -> es

[tylerjl]

I'm moving some small indices (~1-2k documents) to another index and got this stack trace on one of them:

Unfortunately I'm doing these in large batches so I can't pin down the exact index/document for debugging.

Running on version:

@tylerjl Looks you're running into #40. Any further thoughts on that @drewr ?

Yep, confirmed that lowering scroll size fixes this - closing as a duplicate of #40
