Azure模板验证失败，表达式无效

我已导出一个资源组，其中包含一些我想在Visual Studio中使用的逻辑应用程序，但无法使用VS中的designer视图打开一个逻辑应用程序

即使我没有以任何方式修改代码，也会出现此错误：

模板验证失败：“属性”表达式“”[concat（'@equals（toLower（triggerBody（）？[''，参数（'workflows_Booking_name'），'s']？['Event']，'create'））]”” 第“1”行和第“1827”列的模板操作“Condition_-_Create_或_UpdateBookings”不是有效的模板语言表达式。“”

为了更好地理解，这就是Logic应用程序在门户中的外观。

正如Szymon Wylezol提到的，模板本身似乎有问题。从错误消息中我们知道表达式

[concat（'@equals（toLower（triggerBody（）？[''，parameters（'workflows\u Booking\u name'），'s']？['Event']，'create'））不正确。

。有关表达式的更多详细信息，请参阅

根据您提供的屏幕截图，我们可以在代码视图中获得如下表达式：

"actions": {
    "Condition_-_Create_or_UpdateBookings": {
      "type": "If",
      "expression": "@equals(toLower(triggerBody()?['Bookings']?['Event']), 'create')",
      "actions": {},
      "runAfter": {}
    }
  }

请将VS中的代码视图与Azure门户中的代码视图进行比较

然后它就可以在VisualStudio中查看了。有关在Visual Studio中设计、构建和部署Azure Logic应用程序的更多详细信息，请参阅

看起来模板本身有问题。如果仔细查看错误消息，表达式包含[concat（“…”）]，它看起来像ARM模板表达式，而不是逻辑应用程序定义表达式。您能否在代码视图中查看并确认情况是否如此（并与原始逻辑应用程序确认是否相同）？您能否共享该模板？
