Loading WASM in web worker works in dev, but fails in build worker and works in build main.ts

[greenpdx]

I am trying to use WASM in a web worker using wasm-pack in a Vue application.
I have installed 'vite-plugin-wasm'
I am loading wasm in two files main.ts and echoWorker.ts

It works in dev mode, but when I run 'npm run build-only' I get error
'''
error during build:
[vite:worker] Could not load /home/svvs/vue_wasm_template/pkg/wasm_bg.wasm (imported by pkg/wasm.js): "ESM integration proposal for Wasm" is not supported currently. Use vite-plugin-wasm or other community plugins to handle this. Alternatively, you can use .wasm?init or .wasm?url. See https://vite.dev/guide/features.html#webassembly for more details.

• FYI not question
  Also It work in Chromium but but firefox in real time but when I have a break point then run it works. I think the "import * as wasm ...." in echoWorker.ts is creating a race condition in firefox

add to vite.config.ts
worker: {
plugins: [
wasm(),
topLevelAwait()
]
},
