AWS Lambda DynamoDB Boto3 Python

I'm having trouble with I've looked through the documentation and I'm still confused about I'm working on a project and hit a roadblock. I'm working with a timeout behavior when my AWS Lambda function tries to fetch data from DynamoDB using the Boto3 library in Python 3.9. The Lambda function is set to a timeout of 10 seconds, but I'm getting a `Task timed out after 6.00 seconds` behavior. I've ensured that the function has enough permissions to access DynamoDB, and I can confirm that my IAM role has the `dynamodb:GetItem` permission. Here's the relevant code snippet: ```python import json import boto3 def lambda_handler(event, context): dynamo_client = boto3.client('dynamodb') table_name = 'my-table' item_id = event['id'] response = dynamo_client.get_item( TableName=table_name, Key={ 'id': {'S': item_id} } ) return { 'statusCode': 200, 'body': json.dumps(response) } ``` I've tried increasing the Lambda timeout to 20 seconds, but the same timeout behavior continues. Additionally, I verified that the item I'm trying to retrieve exists in the DynamoDB table. When I test the function in the AWS Lambda console, it works correctly, but it's failing when invoked via an API Gateway. Could there be any issues with the API Gateway configuration that might cause this timeout? I've also considered that the cold start scenario might be affecting performance, but I’m not sure how to mitigate that. Any insights would be appreciated! My development environment is Linux. What am I doing wrong? Has anyone else encountered this? Has anyone dealt with something similar?
