Bug Report: Schema Discovery Problem with nested documents (Dremio 3.0.0 and MongoDB 3.6.8)

Has anyone experienced something similar? Are there any workarounds? My team is working on a PoC and this issue is kind of a showstopper to us.

Just for completeness: I simplified the query to make it easy to reproduce. We’re actually trying to do some more complex operations involving parsing timestamp, etc.

Thanks, Tim
