Error: Cannot resolve type entity i1.FontAwesomeModule to symbol

Describe the problem

when I run ng build I get this error

Error: Module build failed (from ../../node_modules/@ngtools/webpack/src/ivy/index.js):
Error: Cannot resolve type entity i1.FontAwesomeModule to symbol
    at node_modules\@ngtools\webpack\src\ivy\loader.js:81:18
    at processTicksAndRejections (node:internal/process/task_queues:96:5)

What did you expect?

to build without errors

Reproducible test case

repo run cd ngx-cms && npm run tmp

@devoto13 Good news is I was able to trigger breakpoint in exception. Thank you very much for this launch configuration thing. Bad news is that I was unable to find that erroneous entity type: in the exception block the context is lost and the place where it happens is emitting polyfills.ts (this is what resourcePath tells me)… Does not help much, alas… Well, don’t want to bother you further with that. UPDATE: I am close to finding the root cause: I just needed to put the breakpoint in chunk-[BLABLA].js file, which creates an interpolation of the error message and then analyzing the call stack.

You’ll need to attach the debugger to the Node process building the application, not to the application running in the browser. If you use VS Code, then something like the below in the .vscode/launch.json should work:

{
    "version": "0.2.0",
    "configurations": [
      {
          "type": "node",
          "request": "launch",
          "name": "ng serve",
          "program": "${workspaceFolder}/node_modules/@angular/cli/bin/ng.js",
          "args": ["serve"]
      }
    ]
}

Add this configuration, open the node_modules@ngtools\webpack\src\ivy\loader.js file in the VS Code, put a breakpoint, run the ng serve configuration inside VS Code.
