Why sometimes the export adds the file "box2d.wasm and box2d.wasm.js" to my HTML5 export?

I see that with these files my server does not work even if I set MIME properly. How can I tell a system to work without it? Because sometimes it exports without these files. What causes the system to export these files?

These are used for the Physics behavior.

See the manual guide on MIME types for correctly configuring web servers.

I found the problem, it happens when I add physics to objects. Is it possible to change the type of physics? Because with this file, it does not work for me on the server.

Thanks!
