_CommonActions.default.createAction不是函数

如何解决_CommonActions.default.createAction不是函数

我有一个带有通用方法的类，需要在另一个类中使用

这里是那些方法的类

 export default class CommonActions {
  constructor(elementFactory) {
    this.elementFactory = elementFactory;
  }
  createAction(type,group,className,title,options) {
    function createListener(event) {
      var shape = elementFactory.createShape(
        (0,_minDash.assign)(
          {
            type: type,},options
        )
      );

      if (options) {
        shape.businessObject.di.isExpanded = options.isExpanded;
      }

      create.start(event,shape);
    }

    var shortType = type.replace(/^bpmn:/,"");
    return {
      group: group,className: className,title:
        title ||
        translate("Create {type}",{
          type: shortType,}),action: {
        dragstart: createListener,click: createListener,};
  }

  createCustomServiceTask(templateId,serviceTaskName) {
    return function (event) {
      const businessObject = bpmnFactory.create("bpmn:ServiceTask",{
        name: serviceTaskName,"camunda:modelerTemplate": templateId,});

      const shape = elementFactory.createShape({
        type: "bpmn:ServiceTask",businessObject: businessObject,});

      create.start(event,shape);
    };
  }
}

这是我尝试使用它的课程

    import {createAction} from './Common/CommonActions'
import {createCustomServiceTask} from './Common/CommonActions'
export default class CustomPalette {
  constructor(bpmnFactory,create,elementFactory,palette,translate) {
    this.bpmnFactory = bpmnFactory;
    this.create = create;
    this.elementFactory = elementFactory;
    this.translate = translate;

    palette.registerProvider(this);
  }

  getPaletteEntries(element) {
    const { bpmnFactory,translate } = this;





    return {
      "create.start-event": createAction(
        "bpmn:StartEvent","event","bpmn-icon-start-event-none",translate("Create StartEvent")
      ),"create.end-event": createAction(
        "bpmn:EndEvent","bpmn-icon-end-event-none",translate("Create EndEvent")
      ),"create.exclusive-gateway": createAction(
        "bpmn:ExclusiveGateway","gateway","bpmn-icon-gateway-none",translate("Create Gateway")
      ),"symphony-separator": {
        group: "symphony",separator: true,"create.validate-room": {
        group: "symphony",className: "bpmn-icon-service-task",title: translate("Symphony - Validate Room"),action: {
          dragstart: createCustomServiceTask(
            "com.avispl.symphony.delegate.camunda.ValidateRoom","Validate Room"
          ),click: createCustomServiceTask(
            "com.avispl.symphony.delegate.camunda.ValidateRoom","create.perform-device-control-check": {
        group: "symphony",title: translate("Symphony - Perform Device Control Check"),action: {
          dragstart: createCustomServiceTask(
            "com.avispl.symphony.delegate.camunda.PerfomrDeviceControlCheck","Perform Device Control Check"
          ),click: createCustomServiceTask(
            "com.avispl.symphony.delegate.camunda.PerfomrDeviceControlCheck","create.perform-device-control-commands": {
        group: "symphony",title: translate("Symphony - Perform Device Control Commands"),action: {
          dragstart: createCustomServiceTask(
            "com.avispl.symphony.delegate.camunda.PerformDeviceControlCommands","Perform Device Control Commands"
          ),click: createCustomServiceTask(
            "com.avispl.symphony.delegate.camunda.PerformDeviceControlCommands","create.perform-device-control-result-verification": {
        group: "symphony",title: translate(
          "Symphony - Perform Device Control Result Verification"
        ),action: {
          dragstart: createCustomServiceTask(
            "com.avispl.symphony.delegate.camunda.PerformDeviceControlResultVerification","Perform Device Control Result Verification"
          ),click: createCustomServiceTask(
            "com.avispl.symphony.delegate.camunda.PerformDeviceControlResultVerification","create.report-success": {
        group: "symphony",title: translate("Symphony - Report Success"),action: {
          dragstart: createCustomServiceTask(
            "com.avispl.workflow.camunda.SuccessDelegate","Report Success"
          ),click: createCustomServiceTask(
            "com.avispl.workflow.camunda.SuccessDelegate","create.report-failure": {
        group: "symphony",title: translate("Symphony - Report Failure"),action: {
          dragstart: createCustomServiceTask(
            "com.avispl.workflow.camunda.FailDelegate","Report Failure"
          ),click: createCustomServiceTask(
            "com.avispl.workflow.camunda.FailDelegate",};
  }
}

CustomPalette.$inject = [
  "bpmnFactory","create","elementFactory","palette","translate",];

我有错

_CommonActions.default.createAction不是函数

我该如何解决？
