stack level too deep error

[Gerald Brown]

I created a myrubyrep.file and then ran: rubyrep scan -c myrubyrep.conf.

I then received the following error: Invalid gemspec in [/usr/share/rubygems-integration/all/specifications/rbnacl-libsodium.gemspec]: stack level too deep
Exception caught: no connection to 'left' database

Both databases are PostgreSQL-11.2 running on Linux Mint 19.1 and I can connect to both left and right with psql. 

I just changed the user name from gerald(me) to postgres and still can not connect to the left database.

Any ideas why this is happening?

Thanks
