s3-bucket | Simple AWS S3 Wrapper | AWS library

I have the following situation:

• An S3 bucket with multiple path-based applications, grouped by version number. Simplified example:

I wish to create an AWS CloudWatch Event rule for S3 create events, in a specific bucket and prefix. Since CloudWatch does not support wildcards, I am instead trying to give the prefix explicitly as in the following example: Does AWS CloudWatch Events Rule supports any wildcards in S3 bucket/key names

(for obfuscation I provide the bucket and prefix names here as my-data-bucket and my-data-prefix/)

My JSON rule:

I'm experimenting with AWS Lambda by following along with the instructions here: https://github.com/awsdocs/aws-lambda-developer-guide/tree/main/sample-apps/java-basic.

Part of the setup instructions require running this script (2-deploy.sh):

I'm trying to host a static react website on an AWS S3 bucket with CloudFront as a front-end.

Additionally the front-end uses an API which runs as a service on a seperate server with a connected domain.

However, when I go to my static s3 website to test it out, I can see in the developer console that all API calls from the bucket to the API are rewritten with the buckets own URL so it's using it own URL instead of the API's URL.

The API url is defined in the environment variables so my first thought was the environment variables are not defined during build. I printed the output of all the environment variables doing the build and they're all correct.

I was looking at a stackoverflow post (react router doesn't work in aws s3 bucket) but unfortunately it didn't help.

Any help or advice would be greatly appreciated.

EDIT My static website hosting settings:

I'm trying to create a gitlab ci/cd pipeline able to upload on Amazon S3 only the edited files. It is a possible thing? If yes, how can I edit my current .gitlab-ci.yml so only the changed files are uploade to ASW S3:

I have a module that creates multiple buckets:

My AWS lambda function MyLambda requires a file called auxiliary.json. I manually created the function and the file in the console and it is working fine.

Now, I would like to do this using CloudFormation so that I can see both the lambda function code and the file content on the console, and it works the same way it does with the manually created one. I do not want to package it with as zip and push it to S3 bucket.

I have the files in my code folder in the following structure:

I'm trying to delete multiple (like: thousands) of files from Amazon S3 bucket. I have a file names listed in a file like so:

I'm trying to write a CloudFormation template to configure an AWS S3 bucket with intelligent tiers configuration, and have read AWS::S3::Bucket IntelligentTieringConfiguration link. However it's not clear where to put in in the YAML file.

I have a template file, and run an AWS CLI command
