aws appsync graphql dynamodb JavaScript

I'm upgrading from an older version and I'm learning this framework and I've looked through the documentation and I'm still confused about I'm currently working with AWS AppSync to set up a GraphQL API, but I'm working with an 'Internal Server behavior' (500) when attempting to execute one of my queries. The query looks like this: ```graphql query GetUser($id: ID!) { getUser(id: $id) { id name email posts { title content } } } ``` The resolver for this query is set up to pull data from a DynamoDB table. Here’s the configuration for my resolver: ```json { "version": "2018-05-29", "operation": "GetItem", "key": { "id": "$ctx.args.id" } } ``` I have verified that the table exists, and I have confirmed that the item with the given ID is present in DynamoDB. Moreover, my IAM role has the necessary permissions to read from the table. However, when I execute the query from the AppSync console, it returns: ``` { "errors": [ { "message": "Internal Server behavior" } ] } ``` To troubleshoot, I enabled logging for the resolver, and the logs indicate that there were no issues connecting to DynamoDB, yet the behavior continues. I also checked for any typos in my DynamoDB table name and key attributes, but everything seems correct. I've tried re-deploying my CloudFormation stack, and I've also checked that the GraphQL schema is correctly defined and matches the resolver configurations. What am I missing here? Is there something specific to AppSync that I need to consider when debugging a 500 behavior like this? My team is using Javascript for this web app. Any suggestions would be helpful.
