Need some help figuring out how to debug this error when running my project. Loading the game in the hosting localhost:8080 results in it crashing immediately.

It works fine on desktop, just not web.

Main error lines:

ERROR: No suitable library found for GDExtension: res://library.gdextension. Possible feature flags for your platform: web, s3tc, nothreads, wasm32, template, debug, template_debug, single

These errors happened later but I don't think they're the cause of the crash.

So, these look like errors from the export process? Web errors currently only show in the browser.

Unfortunately due to #86, web support is a bit borked when working with the rendering server. I don't have any great ways to debug this. Not sure if the issue is emscripten, godot, or the javascript gdextension trampoline I've built.

@nii236 some fixes have been made for web support, please try again to see if you still have this particular issue.
