Try the following:

db.createUser({ user:"userName", 
                pwd:"passWord", 
                roles:[ { role:"readWrite", 
                          db:"dataBaseName" 
                        } ], 
                mechanisms:[ "SCRAM-SHA-1"] 
              })

I had the same issue. You have to switch to a database on your mongo server that actually has the role root because it's saying that the database test, which is selected when you open a MongoDB shell, doesn't have the role root. just try use admin to switch to the admin database and then try db.createUser({ user: "mongoadmin" , pwd: "mongoadmin", roles: ["root"]}), like you posted in the question. That solved my issue.
