我正在尝试利用 apache camel-web3j 组件连接到本地 ganache 测试网节点：https ://github.com/apache/camel/blob/master/components/camel-web3j/src/main/docs/web3j-component .adoc

即使这没有正式发布，我也能够在本地构建它并作为本地依赖项包含在我的 maven 项目中。当我按照 github 网站上的说明进行操作时，我收到错误消息：

我很困惑，因为它首先抛出一个错误，然后说它成功连接。此外，当我将操作更改为ETH_GET_BLOCK_BY_HASH它时，会引发不受支持的操作异常。

我想知道是否有人尝试使用此组件并看到问题？

我使用的端点是： web3j://127.0.0.1:7545?operation=BLOCK_OBSERVABLE
