總是在 aws-cdk 中出現 stack.regionalFact 錯誤

Question

在像cdk-deploy這樣的任何 cdk 命令上，我都會收到此錯誤。 我用cdk innit app --language typescript創建了這個項目。 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(
                 ^
TypeError: Resolution error: Resolution error: Resolution error: Resolution error: stack.regionalFact is not a function.

我只是用 AppSync 創建一個 graphQl api 並用它調用 lambda 函數。

我通過注釋所有代碼然后逐一取消注釋每個構造然后運行cdk deploy來確定我的錯誤發生的位置

所以這是給出錯誤的構造（當取消注釋時，發生錯誤）

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"缺少版本號前的^ ，導致 CDK package 版本沖突。 其他包（帶有carat 符號）已更新到最新的次要版本（當您上次運行npm update時），但core停留在 v1.121.0。
