I’ve got a problem running this tutorial [https://docs.openvidu.io/en/2.16.0/tutorials/openvidu-js-node/](https://docs.openvidu.io/en/2.16.0/tutorials/openvidu-js-node/) and I could not get this working since there is an error like below:  
`TypeError: Cannot read property 'createConnection' of undefined`  
and it is right to inspect this as an error since the `session` has no method named `createConnection`. Working on this for an hour made me believe that there must be a problem in the code provided in this tutorial.I appreciate your help.

These instructions work perfectly fine: [OpenVidu Docs](https://docs.openvidu.io/en/2.16.0/tutorials/openvidu-js-node/)  
Make sure you run those commands and do not change the version of neither openvidu-node-client nor openvidu-server-kms docker image.
