Query Strings Event Values w/Lambda Integration using API Gateway (REST & HTTP API) & Application Load Balancers

This solely tests array query string values since I find these the most interesting edge case. So the query string would be colors[]=blue&colors[]=red for all cases below.

API Gateway HTTP API (version 2.0)

"rawQueryString": "colors[]=blue&colors[]=red",
"queryStringParameters": { "colors[]": "blue,red" }

API Gateway HTTP API (version 1.0)

Aurora Serverless IaC Example Using CDK & TypeScript
// Run `mkdir aurora && cd aurora && cdk init sample-app --language=typescript`
// and replace the `lib/aurora-stack.ts` with this file. May need to remove non-needed
// packages from package.json and add others like "@aws-cdk/aws-rds" and
// "@aws-cdk/aws-secretsmanager"
//
// Running assumes you pass in the following environment variables or hard code values.
//
// * ASCLUSTER_MASTER_USER
// * ASCLUSTER_MASTER_PASS
// * SUBNET_GROUP_NAME
