Did you correctly configure the IP, Port, username, password, dbname of your PostgreSQL in ./config.json (Development) or /usr/local/janusec/config.json (Production), and verified OK by psql -h 127.0.0.1 -U db_user -W janusec
?
Janusec will not create the dbname for you.
If possible, provide a test case for reproducing the error.
