HarmonyOS 意图框架InsightIntentContext.startAbility报错？

Question

参考代码：

export default class IntentExecutorImpl extends InsightIntentExecutor {
  onExecuteInUIAbilityForegroundMode(name: string, param: Record<string, Object>, pageLoader: window.WindowStage): insightIntent.ExecuteResult {
    let want: Want = {
      bundleName: 'xxx',
      moduleName: 'entry',
      abilityName: 'EntryAbility',
      uri: 'xxx'
    };
    //报错
    this.context.startAbility(want)；
    let result: insightIntent.ExecuteResult = {
      code: 0
    };
    return result;
  }
}

报错如下：

Reason:Error
Error name:Error
Error message:Operation not supported.
Error code:

参考demo：

export default class IntentExecutorImpl extends InsightIntentExecutor {
  onExecuteInUIAbilityForegroundMode(name: string, param: Record<string, Object>,
    pageLoader: window.WindowStage): insightIntent.ExecuteResult {
    let want: Want = {
      bundleName: 'xxx',
      moduleName: 'entry',
      abilityName: 'EntryAbility',
      uri: 'xxx'
    };

    try {
      const context = getContext(this) as common.UIAbilityContext;
      context.startAbility(want, (error) => {
        if (error) {
          hilog.error(0x0000, 'testTag', 'Start ability failed with %{public}s', JSON.stringify(error));
        } else {
          hilog.info(0x0000, 'testTag', '%{public}s', 'Start ability succeed');
        }
      })
    } catch (error) {
      hilog.error(0x0000, 'testTag', 'Start ability error caught %{public}s', JSON.stringify(error));
    }

    let result: insightIntent.ExecuteResult = {
      code: 0,
      result: {
        message: 'Execute insight intent succeed.',
      }
    };
    return result;
  }
