UnhandledPromiseRejection if email incorrect inside try..catch

[tandu]

    try {
      return this.mailerService.sendMail({
        to: 'INCORRECT EMAIL HERE',
        subject: 'Password Reset',
        template: 'reset-password-email',
        context: { password }
      });
    }
    catch(e) {
      throw new ForbiddenException(e, 'Email.NotSent');
    }

logs this in nestjs terminal
