wasm-audio-worklet example gives tons of warnings and some errors

[BlinkyStitt]

Motivation

I am trying to use rust in an Audio worklet, but am having trouble.

In Firefox, opening https://wasm-bindgen.netlify.app/exbuild/wasm-audio-worklet/ works although the console gives this warning: "An AudioContext was prevented from starting automatically. It must be created or resumed after a user gesture on the page." But clicking the slider to set volume or frequency does work.

Running locally gives literally over 10k lines of logs.

Opening the page does not work. There is only a white page. The console says there was a panic, so I added console_error_panic_hook to the Cargo.toml and console_error_panic_hook::set_once(); to the main. That gives a slightly more helpful error of getObject(...) is undefined:
