总是在 aws-cdk 中出现 stack.regionalFact 错误

Question

在像cdk-deploy这样的任何 cdk 命令上，我都会收到此错误。 我用cdk innit app --language typescript创建了这个项目。 我的 cdk 版本是 1.121.0

D:\Unicorn\cdk\step03_graphQl\node_modules\@aws-cdk\aws-iam\lib\principals.ts:775
    return stack.regionalFact(
                 ^

我只是用 AppSync 创建一个 graphQl api 并用它调用 lambda 函数。

我通过注释所有代码然后逐一取消注释每个构造然后运行cdk deploy来确定我的错误发生的位置

所以这是给出错误的构造（当取消注释时，发生错误）

const lambda_function = new lambda.Function(this, "LambdaFucntion", {
  runtime: lambda.Runtime.NODEJS_14_X, ///set nodejs runtime environment
  code: lambda.Code.fromAsset("lambda"), ///path for lambda function directory
  handler: "index.handler", ///specfic fucntion in specific file
  // timeout: cdk.Duration.seconds(10), ///Time for function to break. limit upto 15 mins
});

"@aws-cdk/core": "1.121.0"缺少版本号前的^ ，导致 CDK package 版本冲突。 其他包（带有carat 符号）已更新到最新的次要版本（当您上次运行npm update时），但core停留在 v1.121.0。
