I deployed my backend server on google cloud engine and it generated an https. I am unable to use this with Websocket javascript library at frontend (react) and generates the following error:

SyntaxError: Failed to construct 'WebSocket': The URL's scheme must be either 'ws' or 'wss'. 'https' is not allowed.

Please tell me if there is a workaround.

https link generated from google cloud engine where my golang backend server is: 'https://project-name'
websocket currently being initialized by:

var socket = new WebSocket('ws://localhost:9000/ws');

That does not work because the backend server is deployed at 'https://project-name' only. 'wss://project-name' would be non-existent. – Tasbiha May 14 '23 at 17:34
Use `var socket = new WebSocket('wss://project-name/ws');` to connect to the websocket endpoint `/ws` on the server `https://project-name`. – Charlie Tumahai May 14 '23 at 17:40
Is it Compute Engine or App Engine? – guillaume blaquiere May 14 '23 at 18:30
Sorry, I understood with the URL provided!! It's App Engine. WebSocket is not supported on App Engine, use Cloud RUn instead. – guillaume blaquiere May 14 '23 at 18:31
