My webgl app throws error :TypeError: Module.asm.$a is undefined

The webgl app I deployed is not functioning. The app works fine when built for Android and deployed to the Playstore. I have tried updating the editor, building uncompressed, and a few other things. No luck at all. Any help would be greatly appreciated.

  TypeError: Module.asm.$a is undefined

updated editor. NOt sure what to do. I have a working webgl app I built a few years back that worked fine.

    The issue was that the server was not configured for web assembly files (/wasm) and this was resolved by adding a htaccess file to the game directory as described in the Unity manual here.
