推荐答案

当人们无意中删除了顶级策略并删除了适用于所有api上的所有操作的主要转发请求策略时，就会出现此问题.只需单击添加策略"按钮即可在顶级范围内重新添加默认策略.

This problem occurs when people unintentionally delete the top level policy and remove the main forward-request policy that applies to all operations on all apis. Simply click the Add policy button to re-add the default policy at the top level scope.
