问题描述
我具有预注册功能，可以将用户添加到用户组。我通过CLI添加策略以授权功能更新用户池组，但是，出现以下错误：
> Could not get policies for auth: userPoolGroups Policies cannot be
> added for auth TypeError: Cannot destructure property
> `serviceWalkthroughFilename` of 'undefined' or 'null'.

https://github.com/aws-amplify/amplify-cli/issues/165 在这里，我发现放大功能尚未实现，他们建议添加策略以授权功能调用auth。 在这种情况下，我正在关注：
? Select which capability you want to update: Lambda function (serverless function)
? Select the Lambda function you want to update funcPreSignup
? Do you want to update the Lambda function permissions to access other resources in this project? Yes
? Select the category auth
? Auth has 2 resources in this project. Select the one you would like your Lambda to access projauth
? Select the operations you want to permit for projauth create,read,update,delete
You can access the following resource attributes as environment variables from your Lambda function
AUTH_PROJ_USERPOOLID
? Do you want to invoke this function on a recurring schedule? No
? Do you want to configure Lambda layers for this function? No
Error: Cannot add funcPreSignup due to a cyclic dependency

There was an error adding the function resource
即使我看到它修改了CloudFormation堆栈，它仍然会继续错误显示授权异常
