Current behaviour 💣
When I attempt to build my project, I find the following error:
TypeError: childCompilation.errors.map is not a function

Looking at the code, it appears that the code expects childCompilation.errors to be an array, but it is actually an iterator, which doesn't (yet) have a map method.
Expected behaviour ☀️
If I make the minimal change to get this working - changing childCompilation.errors.map to Array.from(childCompilation.errors).map - I get the compiler error I was expecting:
Failed to compile, check the errors for troubleshooting.
× JSONError { path: "/cloudide/workspace/fe_mono/apps/bernardTem/tsconfig.json", message: "invalid type: string \"./src/*\", expected a sequence at line 15 column 29", line: 15, column: 29 }
Reproduction Example 👾
I don't know how to easily reproduce this in a public fashion, because I have a Typescript project. The underlying reason for the error is that I set an entry in the compilerOptions.paths.[path] of tsconfig.json to be a string rather than an array of strings. See the following:
{
"extends": "@modern-js/tsconfig/base",
"compilerOptions": {
"esModuleInterop": true,
"declaration": false,
"jsx": "preserve",
"baseUrl": "./",
"paths": {
// "@/*": [
// "./src/*"
// ],
"@shared/*": [
"./shared/*"
],
"@project/*": "./src/*",
"@components/*": [
"./src/components/*"
],
"@constants/*": [
"./src/common/constants/*"
],
"@imgs/*": [
"./src/common/imgs/*"
],
"@models/*": [
"./src/models/*"
],
"@utils/*": [
"./src/common/utils/*"
],
}
},
"include": [
"src",
"shared",
"config"
]
}
The error entry is "@project/*": "./src/*". Changing that to "@project/*": ["./src/*"] fixes the compilation error.
Environment 🖥
- Node.js v16.20.2
- linux 5.4.210.bsk.8-sign-amd64
- Webpack: 8.19.4
- I am using rspack 0.6.1 rather than webpack.
- Using https://github.com/rspack-contrib/html-rspack-plugin 5.6.2, which is a fork of this plugin that is kept pretty closely up-to-date. The code throwing an exception is the same in both forks.
I am fine with fix, but will be great to open an issue in rspack too
