HarmonyOS promptAction.openCustomDialog自定义弹窗在非UI类中调用问题

在非UI class中使用打开自定义弹窗

promptAction.openCustomDialog({
  builder:
  MyGlobalBuilderFunction()
,
  onWillDismiss:(dismissDialogAction: DismissDialogAction) => {
    console.info("reason" + JSON.stringify(dismissDialogAction.reason))
    console.log("dialog onWillDismiss")
    if (dismissDialogAction.reason == DismissReason.PRESS_BACK) {
      dismissDialogAction.dismiss()
    }
    if (dismissDialogAction.reason == DismissReason.TOUCH_OUTSIDE) {
      dismissDialogAction.dismiss()
    }
  }
}).then((dialogId: number) => {
  console.log('')
})

@Builder function MyGlobalBuilderFunction() {
  Column() {
    Text('弹窗').fontSize(30)
    Row({ space: 50 }) {
      Button("确认").onClick(() => {
        // promptAction.closeCustomDialog(0)
        // this.controller.open();
      })
      Button("取消").onClick(() => {
        // promptAction.closeCustomDialog(1)
      })
    }
  }.height(200).padding(5).justifyContent(FlexAlign.SpaceBetween)
}

报错：Cannot read property observeComponentCreation2 of undefined
