Unable to forward request for with-db transaction

#1

I was getting unavailable anomalies like the following adding some fixtures to the DB, so tried testing with with-db.

CompilerException clojure.lang.ExceptionInfo: Unable to forward request 
#:cognitect.anomalies{:category :cognitect.anomalies/unavailable, :message 
"Unable to forward request"}

I still get this and an even stranger HTTP connection error (linked below) even for with-db operations, what else could this be caused by?

Hm, I guess with-db does not mean nothing crosses the wire, since datomic code isn’t on my system I guess it has to run on datomic cloud and just not be persisted, is this correct?

Would still appreciate help understanding the errors – they happen consistently.
