The method getParsedBody() does not exist on Psr\Http\Message\RequestInterface. It seems like you code against a sub-type of Psr\Http\Message\RequestInterface such as Psr\Http\Message\ServerRequestInterface or GuzzleHttp\Psr7\ServerRequest.

The method findByLogin() does not exist on Yiisoft\Auth\IdentityRepositoryInterface. It seems like you code against a sub-type of Yiisoft\Auth\IdentityRepositoryInterface such as App\User\UserRepository.

                if ($identity !== null) {
                    throw new \InvalidArgumentException('Unable to register user with such username.');
