The @search directive on the currentPrice edge seems to be the/an issue. I’m not seeing the exact result you experienced: dgraph reports an error (the container exits and restarts) and I get back empty results, not just inaccurate results like you’re seeing.
If I use the 21.03.01 version image (instead of the 21.03.0 version), no issues exist. I believe the cloud is on 21.03.0 – but I can’t confirm that because I’m unable to log into cloud.dgraph.io at the moment
