Hyperledger Fabric：无法执行交易：超时已过期

Question

我一直在使用 Hyperledger Fabric，我的链码涉及复杂的计算，需要时间。我希望在配置中增加超时时间，以便事务可以工作。这是错误和它之前的一些日志：

类似的问题可以在这里找到。截至目前，我已尝试在core.yaml 中增加各种超时时间，但似乎没有任何效果。我想知道具体是哪个超时导致了这个问题以及如何解决这个问题？

Answer 1

chaincode由于您chaincode的崩溃，您必须有错误。类似的案例也发生在我身上。通常，如果您的链码崩溃，您的交易将超时。

要调试，请通过以下方式列出所有 docker 容器：

docker ps

复制chaincode容器的id并执行以下命令：

docker attach <container-id> -f

再次执行调用/查询命令。如果发生崩溃，日志将打印在您执行的位置docker attach
