Class constructor NgbDatepickerConfig cannot be invoked without 'new'

After updating to Angular 13 and ng-bootstrap to v11.0.0 (as stated here one should use v11.0.0 for Angular 13 and bootstrap 4) I get the following error in jest(v27.5) tests:

TypeError: Class constructor NgbDatepickerConfig cannot be invoked without 'new'

       5 | export class DefaultDatepickerConfig extends NgbDatepickerConfig {
       6 |   constructor() {
    >  7 |     super();
         |     ^

Tried to use 11.0.0-rc.0 - didn't helped. Got another error.

Any thoughts on how to fix this issue?

Solution

  • There's no answers here so I'm going to answer my own question.

    So I've found a fix for this problem. Changing "compilerOptions": { "target": "es5"} to es2015 in my tsconfig.json file helped. It solved the problem immediately
