Getting error: You may need an additional loader #20471
Description
I am getting the following error.
You can reproduce it with this minimal GitHub repository:
https://github.com/csname1910/errordemo
Error: ./node_modules/pdfjs-dist/build/pdf.js 2413:45
Module parse failed: Unexpected token (2413:45)
File was processed with these loaders:
* ./node_modules/@angular-devkit/build-angular/src/babel/webpack-loader.js
* ./node_modules/@ngtools/webpack/src/ivy/index.js
You may need an additional loader to handle the result of these loaders.

Heya, the optional chaining syntax is not supported by Webpack 4, see webpack/webpack#10227, and that is used in the Angular CLI. Support for Webpack 5 is currently experimental in Angular CLI 11.

Indeed as @JoostK mentioned the optional chaining is not support by Webpack 4 which is used in the Angular CLI 11, to opt-in using experimental support for Webpack 5 which is not recommended to be used for production. See: #18820.
In version 12, the Angular CLI will use Webpack 5 which does support the mentioned syntax see: #20466
