		$data = $response->getData();

		return new EchoResponse(
			DateTimeImmutable::createFromFormat('YmdHis', $data['dttm']),

It seems like DateTimeImmutable::createFromFormat('YmdHis', $data['dttm']) can also be of type false; however, parameter $responseDateTime of SlevomatCsobGateway\Call\EchoResponse::__construct() does only seem to accept DateTimeImmutable, maybe add an additional type check?

			ResultCode::get($data['resultCode']),
			$data['resultMessage']
		);
