_bg.wasm Unexpected section: 0x86

[kpp]

How to reproduce:

cd ~/wasm-bindgen/examples/webaudio
npm install
npm build

Output:

ERROR in ./pkg/webaudio_bg.wasm
Module parse failed: Unexpected section: 0x86
You may need an appropriate loader to handle this file type.
Error: Unexpected section: 0x86

    at Object.decode (~/wasm-bindgen/examples/webaudio/node_modules/@webassemblyjs/wasm-parser/lib/decoder.js:1559:25)

Because of (I believe so):

$ head -n2 pkg/webaudio.js
/* tslint:disable */
import * as wasm from './webaudio_bg';

How do I fix it?

Well. Looks like I failed twice reporting the issue. Duplicate of #1249

Are you sure this is a duplicate of another bug?

I had a similar issue, regarding WASM module parse failure. It turned out it was the old version of wasm-parser npm package. Updating webpack to 4.29.4 (which has a newer wasm-parser version as a dependency) fixed this issue.

It seems the webpack version in examples/webaudio has already been bumped in 5e7187a.

How to update it?

[BigBigos]

Open package.json and update the webpack version inside:

    "webpack": "^4.29.4",

Or, if you just want to run the webaudio example, pull the recent changes from this repo as it has already been bumped 20h ago.
