Cassandra client error on NodeJS

Trying to use cassandra driver 3.5 in a nodejs app. When instantiating the client via cassandra.Client({}), it erros with:

TypeError: Cannot read property 'bind' of undefined
at Object.Client (....path..../lambdas/data-upload/node_modules/cassandra-driver/lib/client.js:307:63)

line 307 of the client code is:

this.options = clientOptions.extend({ logEmitter: this.emit.bind(this) }, options);

so the "this.emit.bind" is where it is failing.

The environment is node 8.10 (tried 8.11 as well) and driver version 3.5 (tried 3.4 but has same code).

Found the problem, after about 8 hours of digging. I wasn't "new"ing the class.

I was doing: 

const client = cassandra.Client(....)

instead of (correct)

const client = new cassandra.Client(....)
