It seems like $rocket->getDestinationOrigin() can also be of type null; however, parameter $message of Yansongda\Pay\verify_wechat_sign() does only seem to accept Psr\Http\Message\ResponseInterface|Psr\Http\Message\ServerRequestInterface, maybe add an additional type check?

        $body = json_decode((string) $rocket->getDestination()->getBody(), true);

The method getBody() does not exist on Yansongda\Supports\Collection.

        $rocket->setDirection(NoHttpRequestDirection::class)->setPayload(new Collection($body));

        $body['resource'] = decrypt_wechat_resource($body['resource'] ?? [], get_provider_config('wechat', $params));

        $rocket->setDestination(new Collection($body));

        Logger::info('[Wechat][V3][CallbackPlugin] 插件装载完毕', ['rocket' => $rocket]);

        return $next($rocket);
    }

        $request = $rocket->getParams()['_request'] ?? null;
        $params = $rocket->getParams()['_params'] ?? [];

        if (!$request instanceof ServerRequestInterface) {
            throw new InvalidParamsException(Exception::PARAMS_CALLBACK_REQUEST_INVALID, '参数异常: 微信回调参数不正确');
        }

        $rocket->setDestination(clone $request)
            ->setDestinationOrigin($request)
            ->setParams($params);
    }
