Assets path for .wasm file incorrect for subdirectories

[justindthomas]

For paths like server.name/path, the wasm modules load fine (from server.name/assets/module_bg.wasm). But for paths like server.name/enitity/3324-3252-2352-2352, Vite tries to load the wasm modules from server.name/entity/assets/module_bg.wasm, which fails.

This is only evident on the production server - when I run yarn dev in SvelteKit, everything works fine. But running on the node adapter, this breaks. I've tried all the configuration changes I can think of to get it to point to the right place (e.g., base: "", explicit assets path, etc.) but nothing I do seems to have any effect.

Working example in dev:

My vite.config.js looks like this:

import { sveltekit } from '@sveltejs/kit/vite';
import { defineConfig } from 'vite';
import wasmPack from 'vite-plugin-wasm-pack';
import inject from '@rollup/plugin-inject';

export default defineConfig({
	plugins: [wasmPack('./wasm/enigmatick_wasm'), wasmPack('./wasm/enigmatick_olm'), sveltekit()],
	resolve: {
		alias: {
			path: 'path-browserify'
		}
	},
	build: {
		rollupOptions: {
			plugins: [inject({ Buffer: ['buffer', 'Buffer'] })]
		}
	},
})

Note that this is the only page I have that's two levels deep. All of the other pages at just one level work fine. Is there something I can do to fix this?
