Migrating from createContainer to withTracker in Meteor / React

Meteor / React newb here and I'm having a problem upgrading from createContainer (which is depreciated) to withTracker in the following.

export default createContainer(() => {
  Meteor.subscribe('users', PER_PAGE);

  return { users: Users.find({}).fetch() };
}, UsersList);

I've tried the following...

import { withTracker } from 'meteor/react-meteor-data';

.....

export default withTracker(() => {
  Meteor.subscribe('users', PER_PAGE);

  return { users: Users.find({}).fetch() };
}, UsersList);

but I'm getting errors in the console : 

Warning: Functions are not valid as a React child. This may happen if you return a Component instead of <Component /> from render. Or maybe you meant to call this function rather than return it.

Could somebody show me where I'm going wrong please?

This seems to be a syntax error in the last line of your code snippet

export default withTracker(() => {
  Meteor.subscribe('users', PER_PAGE);

  return { users: Users.find({}).fetch() };
}, UsersList);

Replace it with 

export default withTracker(() => {
  Meteor.subscribe('users', PER_PAGE);

  return { users: Users.find({}).fetch() };
})(UsersList);
