webpack - Error when using web workers with Angular, transpiler removes a piece of code

Question

I've got the following code in my Angular application:

      const worker = new Worker("./filter.worker.ts", {
        type: "module",
      });

Which Angular transpiles to the following:

  var worker = new Worker(__webpack__worker__0, {
            ,
        });

And that gives me an error in the browser SyntaxError: Unexpected token ','

I have the following versions of angular packages:

  "@angular/cdk": "^8.2.3",
  "@angular/common": "^8.2.14",
  "@angular/compiler": "^8.2.14",
  "@angular/core": "^8.2.14",
  "@angular-devkit/build-angular": "^0.803.25",
  "@angular/cli": "^8.3.25",
  "@angular/compiler-cli": "^8.2.14",
  "@angular/language-service": "^8.2.14",

Solved by removing the comma:

const worker = new Worker("./filter.worker.ts", {type: "module"});
