Question

我正在努力阅读从链码返回的状态码。

我正在使用结构节点SDK进行以下调用：

results = await channel.sendTransactionProposal(request);

其中channel是节点SDK中的Channel对象。我的链码拒绝了该请求，并返回HTTP状态码500。节点SDK抛出未设置状态码的异常。深入研究代码，我在Fabric-client的Peer.js中发现了以下代码，该代码引发错误：

if (proposalResponse) {
    logger.debug('%s - Received proposal response from peer "%s": status - %s', method, self._url, proposalResponse.response.status);
    // 400 is the error threshold level, anything below that the endorser will endorse it.
    if (proposalResponse.response && proposalResponse.response.status < 400) {
        resolve(proposalResponse);
    } else if (proposalResponse.response && proposalResponse.response.message) {
        reject(new Error(proposalResponse.response.message));
    } else {
        logger.error('GRPC client failed to get a proper response from the peer "%s".', self._url);
        reject(new Error(util.format('GRPC client failed to get a proper response from the peer "%s".', self._url)));
    }
} else {
    logger.error('GRPC client got a null or undefined response from the peer "%s".', self._url);
    reject(new Error(util.format('GRPC client got a null or undefined response from the peer "%s".', self._url)));
}

第reject(new Error(proposalResponse.response.message));行引发了错误，并且状态代码显然丢失了。这是在fabric-client的1.2.2版本上，可以在这里找到： https://github.com/hyperledger/fabric-sdk-node/tree/v1.2.2

是否有任何解决方法，还是我们必须等待更新的版本？看来该问题已在v1.3中解决（是否仅与Fabric v1.3兼容？

谢谢
