Upgrade(2.14.0 to 2.15.0) openvidu version which deploy on aws

I had done deployment earlier on AWS. Now I am working on front end with insecure js. I am getting DOM exception error (your server version is 2.14.0 and front-end version is 2.15.0).

Please give me steps to upgrade version on server(AWS) end.

Almost everything is published in the official documentation

https://docs.openvidu.io/en/2.15.0/openvidu-pro/deployment/upgrading/#migrating-from-2140-to-2151

You need to update the frontend dependency.:
Change this:

<script src="openvidu-browser-2.14.0.js"></script>

To this:

<script src="openvidu-browser-2.15.0.js"></script>

The js is in the tutorial repository:
