datomic pro unsupported protocol issue

[lenw]

I have the datomic pro version building from source with no issues however when I try to connect to a url like

datomic:sql://test?jdbc:postgresql://db.example.com:5432/datomic?user=datomic&password=datomic

or

datomic:dev://localhost:4334/test

I get an exception trying to connect

:cause :db.error/unsupported-protocol Unsupported protocol :sql

I assume that the classes are not loaded correctly at the time of connect - any ideas on how to proceed ?

We meet again. Such Empty! Did you find a solution? Best :)
Edit
I found success with the below combination of addition deps in my project :
[com.datomic/client-pro "0.8.28"]
[luminus-immutant "0.2.5"]
[ring/ring-core "1.7.1"]]
connecting to a dev backed db with (d/connect (d/client cfg) {:db-name dbname}), supplying accesskey and secretkey.. 👍 Happy hunting!
