# Starting datomic:free://localhost:4334/<DB-NAME>, storing data in: data ...
# System started datomic:free://localhost:4334/<DB-NAME>, storing data in: data

# Run the rest client with the datomic db uri from above (port could differ)
bin/rest 4619 test datomic:free://localhost:4334
# Should say:

# Restart rest with trailing slash:

REST API started on port: 4619
   test = datomic:free://localhost:4334/

On line 17, I think you need the -p port switch as it:
bin/rest -p 4619 test datomic:free://localhost:4334
