在 aws-cdk 中总是出现 stack.regionalFact 错误

Question

在任何像 cdk-deploy 这样的 cdk 命令上我得到这个错误。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一个一个地取消对每个构造的注释然后运行 cdk deploy

确定了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"版本号前缺少^，导致CDK包版本冲突。其他软件包（带有 carat symbol）已更新到最新的次要版本（上次运行 npm update），但 core 停留在 v1.121.0。
