Amazon cloudformation 云层形成产生了；无效的模板属性或属性"；错误

我从下面的cloudformation模板中获得“一个或多个无效的模板属性[TestLambda]”。我已经用一个在线json验证器验证了json。我试着一个接一个地删除属性，但仍然得到错误。错误消息在诊断问题时无效

有人知道问题出在哪里吗

谢谢

TestLambda

资源实际上在

resources

JSON对象之外。因此，它在AWS端的JSON验证失败，出现了意外的属性

在

资源中移动
TestLambda
将解决此问题

希望这有帮助
 这就是问题所在。现在，我在部署过程的后面遇到了另一个失败。aws cloudformation验证模板毫无价值。
