Node.js cannot read property 'then' of undefined

I try to use a global function where i can use for some mysql functions, but the problem is that js say that the ".then" is undefined, what make i wrong, is this only an syntax error?

 static connectWidthCortex(){
  xdevapi.getSession({
        host: 'localhost',
        port: 33060,
        dbUser: 'admin',
        dbPassword: 'xxxx'
    }).then((session)=> {
  return session.getSchema("cortex");
});
};

static createCollection(collname){
    this.connectWidthCortex().then((db)=> {
  console.log("Cortex connected")
  return db.createCollection(collname);
}).catch((err)=> {
  console.log("connection failed")
});
}

Thx for help :)
