Try the following:

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

"mechanisms" is not a valid argument to createUser – Flint May 06 '20 at 16:06
It is a valid argument. Please kindly review this article: `https://docs.mongodb.com/manual/core/security-scram/` – floss May 06 '20 at 20:13

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.

You can see this more by starting your mongo shell and typing `show roles`. That lists all of the roles available on your currently selected database instance. – StevenBoyce Dec 12 '20 at 14:49

Instead of "root" provide readWrite access to the user:

db.createUser({user: 'userName',pwd: 'somePassword',roles: [{  role: 'readWrite',  db: 'databaseName'}]})
