Yes, the support on this slack channel is pretty non-existent, at least for me. I've posted multiple questions and received no reply. That has prompted me to make the decision to not implement elementary, at least not right now. I may later implement it in an environment where it is by itself. It looks pretty nifty, but, "no support" puts a big stain on the nifty.
Anyways, at a minimum, you should post the query that gave you that problem. That looks like a BigQuery message?
