aws cdk dynamodb TypeScript

I'm attempting to set up I'm upgrading from an older version and I'm stuck on something that should probably be simple....... I'm trying to deploy an AWS CDK stack that creates a DynamoDB table, but I'm working with an behavior that says `Resource handler returned message: "Invalid request"`. The stack gets exploring in the `ROLLBACK_COMPLETE` state, and I need to figure out what went wrong. My CDK version is `2.30.0`, and I'm using TypeScript for my infrastructure code. Here's the snippet of the code that creates the DynamoDB table: ```typescript import * as cdk from 'aws-cdk-lib'; import * as dynamodb from 'aws-cdk-lib/aws-dynamodb'; import { Construct } from 'constructs'; export class MyStack extends cdk.Stack { constructor(scope: Construct, id: string, props?: cdk.StackProps) { super(scope, id, props); const myTable = new dynamodb.Table(this, 'MyTable', { partitionKey: { name: 'id', type: dynamodb.AttributeType.STRING }, billingMode: dynamodb.BillingMode.PROVISIONED, readCapacity: 5, writeCapacity: 5, }); } } ``` I've confirmed that the AWS credentials I’m using have permission to create DynamoDB tables. Additionally, I verified that no other stack or resources are conflicting with the DynamoDB name. I tried changing the `billingMode` to `PAY_PER_REQUEST`, but it resulted in the same behavior. I also checked the CloudFormation events and saw a related message: `ValidationException: The provided key element does not match the schema`. Could this be related to the table schema? I'm considering whether the `partitionKey` needs to be defined differently. Has anyone else encountered this scenario, and what are the best practices for setting up a DynamoDB table using AWS CDK? Any help would be appreciated! This issue appeared after updating to Typescript stable. Thanks in advance! I'm coming from a different tech stack and learning Typescript. I'd be grateful for any help.
