Solution

  • I had the same issue.
    I was going through comments here https://github.com/angular/angular/issues/35399 for solution.

    I simple ran ng serve --prodand the error was gone. After that I even ran ng serve.
    Other solutions proposed are

    • Ensure that the tsconfig.json of your library has set "importHelpers": true
    • Add "enableIvy": false to compilerOptions in tsconfig.app.json
