Hi! Running JanusGraph 0.5.3 against BigTable, and ES is used as the Index backend. For a particular traversal I'm seeing the error message below. No clue what this means and where to look for a solution. Any assistance will be greatly appreciated! Thanks, Assaf

This is all I have in Stackdriver. If there's a way to see more details logs from inside the container, please tell how to get them and I'll gladly post them here.
At first I thought it might have something to do with 2 new indices I added yesterday, so I re-indexed them just in case. But the result is still the same. I'm having a hard time what does the error means - is it an issue with a composite index? a mixed index? which index?
The same traversal steps worked in a development Janus container (whichever storage and index that come out of the box)
