When you suffer from the “API: s3:PutBucketPolicy Access Denied” error while creating a new S3 bucket, how can we resolve it?

The user encountered an error when trying to create a new Amazon S3 bucket for hosting a website. The error message indicated an “Access Denied” issue with the `s3:PutBucketPolicy` API. To resolve this, the user needs to add the `blockPublicAccess` attribute with the value `BlockPublicAccess.BLOCK_ACLS` to the CDK project configuration. By doing so, the default configuration of Amazon S3 will be updated correctly. The user provided additional links as references for more information on this topic.

AWS AWS CDK Hono / Sonik JavaScript

Deploy Sonik application to AWS Lambda with functions URL by AWS CDK

Sonik is a JavaScript meta framework maintained by Yusuke-san, Hono framework maintainer. It allows building websites and web applications with Next.js-like file-based routing and Hono-like REST API. The text provides instructions on how to configure an AWS CDK project and deploy a Sonik app to AWS. It includes code snippets for defining AWS Lambda and Amazon S3 resources, as well as setting up static asset deployment. The text also mentions updating the Sonik app to adapt to AWS Lambda by adding a new entry point file, setting the handler function for mapping requests and responses, and adding a middleware to support static assets deployed to S3. It suggests using CloudFront for distributing static assets in a production environment.

Format Lambda invocation input from EventBridge using AWS CDK

Amazon EventBridge can be customized to transform input parameters using an “input transformer.” The transformer allows the input parameter to be defined the same way as a direct invocation or API Gateway input. To define the input transformer, the AWS CDK can be used with the appropriate code. The input parameter format can be defined as text using RuleTargetInput.fromText instead. The input transformer is useful for obtaining the input parameter the way you want it instead of the default parameter provided by EventBridge.
