Details
In attempt to migrate from webpack I stumbled upon the following error that is a little bit hard to trace, but the root cause is the following:
ts-loader allows to provide options.getCustomTransformers as function.
{
test: /\.tsx?$/,
loader: 'builtin:swc-loader',
type: 'javascript/auto',
options: {
getCustomTransformers: () => {}
...
...
Starting the web server results in the following error:
/Users/user/PATH/node_modules/.pnpm/@rspack+core@1.0.13/node_modules/@rspack/core/dist/index.js:17883
this.#instance = new instanceBinding.Rspack(
