Typescript Super is undefined when running unit tests with jest

I use super.catch inside catch from derived class. And code works fine when I do manual testing. But when I run jest unit tests it says that super is undefined. Does anyone know why? And how it can be fixed?

Code example:

export class CustomExceptionsFilter extends BaseExceptionFilter {
  catch(exception: Error | HttpException, host: ArgumentsHost) {
    logger.error(exception);
    super.catch(exception, host);
  }
}

Unit test example:

beforeEach(async () => {
    filterInstance = new CustomExceptionsFilter();
    host = mockArgumentsHost;
});

it('Test', async () => {
    const baseClassSpy = jest.spyOn(CustomExceptionsFilter.prototype, 'catch');
    const httpException = new HttpException('Test exception', 404);
    filterInstance.catch(httpException, host);
    expect(baseClassSpy).toHaveBeenCalled();
  });

Error I get:

TypeError: Cannot read properties of undefined (reading 'reply')

  36 |     logger.error(exception);
> 37 |     super.catch(exception, host);
     |                ^
