Bug: `deleteOrigianlAssets: true` breaks the build badly...

[mman]

Bug report

Created an empty npx create-react-app@latest webpack-compress-test, added this plugin and broke the build.

Looks like CompressionPlugin is racing with HtmlWebpackPlugin and deletes original .js files too early... before HtmlWebpackPlugin gets a chance to process them.

Steps to reproduce:

1. Create new react app:

€ npx create-react-app@latest webpack-compress-test

Creating a new React app in /Users/mman/Developer/webpack-compress-test.

Installing packages. This might take a couple of minutes.
...

2. Add compression plugin dependency:

€ npm install compression-webpack-plugin --save-dev
added 5 packages, and audited 1561 packages in 2s
...

3. Eject config to get access to webpack.config.js

€ npm run eject

> [email protected] eject
> react-scripts eject

NOTE: Create React App 2+ supports TypeScript, Sass, CSS Modules and more without ejecting: https://reactjs.org/blog/2018/10/01/create-react-app-v2.html

✔ Are you sure you want to eject? This action is permanent. … yes
Ejecting...
...

4. Try to build:

€ npm run build

> [email protected] build
> node scripts/build.js

Creating an optimized production build...
Compiled successfully.
...

5. Examine output:

€ ls -l build/static/js 
total 1064
-rw-r--r--  1 mman  staff    4542 May 22 12:42 453.80dd94dc.chunk.js
-rw-r--r--  1 mman  staff   10597 May 22 12:42 453.80dd94dc.chunk.js.map
-rw-r--r--  1 mman  staff  143827 May 22 12:42 main.2663d1cb.js
-rw-r--r--  1 mman  staff     971 May 22 12:42 main.2663d1cb.js.LICENSE.txt
-rw-r--r--  1 mman  staff  371868 May 22 12:42 main.2663d1cb.js.map

6. Enable compression plugin:

Now modify the config/webpack.config.js and enable compression plugin as the last step to compress everything.

+const CompressionPlugin = require("compression-webpack-plugin");

...
+        new CompressionPlugin({
+          threshold: 0,
+          deleteOriginalAssets: true,
+        })
+

7. Try to build:

€ npm run build

> [email protected] build
> node scripts/build.js

Creating an optimized production build...
Failed to compile.

Cannot destructure property 'info' of 'compilation.getAsset(...)' as it is undefined.

Actual Behavior

Build fails:

€ npm run build

> [email protected] build
> node scripts/build.js

Creating an optimized production build...
Failed to compile.

Cannot destructure property 'info' of 'compilation.getAsset(...)' as it is undefined.

Expected Behavior

Build should succeed with all files being .gzipped
