Thingsboard自定义规则节点-定义的配置指令'myTestNodeConfig'不可用

Question

我在https://thingsboard.io/docs/user-guide/contribution/rule-node-development/之后创建了自定义RuleNode 在部署和运行时，以及在插入“自定义规则”节点时，都会显示

定义的配置指令'myTestNodeConfig'不可用。

在rule-node-examples项目中，定义如下

@RuleNode(
        type = ComponentType.FILTER,
        name = "MyTestNode",
        relationTypes = {"True", "False"},
        configClazz = MyTestNodeConfiguration.class,
        nodeDescription = "Checks the existence of the selected key in the message payload.",
        nodeDetails = "If the selected key  exists - send Message via <b>True</b> chain, otherwise <b>False</b> chain is used.",
        uiResources = {"static/rulenode/custom-nodes-config.js"},
        configDirective = "myTestNodeConfig")
public class MyTestNode implements TbNode {

在rule-node-examples-ui项目中，其定义如下所示

import CheckKeyConfigDirective from './check-key-config.directive';
export default angular.module('thingsboard.ruleChain.config.filter', [])
.directive('myTestNodeConfig', CheckKeyConfigDirective)
    .name;

有人可以帮助您找出缺少的内容。谢谢
