AWS Lambda Function scenarios with 502 scenarios When Accessing API Gateway Endpoint
I've tried everything I can think of but I'm working on a personal project and I am working with a persistent 502 Bad Gateway behavior when trying to invoke my AWS Lambda function through an API Gateway endpoint. The Lambda function is supposed to fetch data from a DynamoDB table and return it as a JSON response. I've tested the Lambda function directly in the AWS console, and it works perfectly with no errors, but when invoked via the API Gateway, I see the following behavior in the CloudWatch logs: ``` START RequestId: 1234-5678-9101-1121 Version: $LATEST END RequestId: 1234-5678-9101-1121 REPORT RequestId: 1234-5678-9101-1121 Duration: 3.45 ms Billed Duration: 4 ms Memory Size: 128 MB Max Memory Used: 45 MB [behavior] 502: Bad Gateway ``` I've set up the API Gateway to use a Lambda Proxy integration, and my Lambda function's code is as follows: ```python import json import boto3 def lambda_handler(event, context): dynamodb = boto3.resource('dynamodb') table = dynamodb.Table('MyTable') response = table.scan() return { 'statusCode': 200, 'body': json.dumps(response['Items']) } ``` I've confirmed the IAM roles are correctly configured, allowing the Lambda function to read from the DynamoDB table. The API Gateway is configured with the appropriate resource path and method (GET). I've also tried enabling CORS, but the behavior remains. In the API Gateway stage, I have set the cache settings to disable caching. I've followed various tutorials and the AWS documentation, but I'm exploring and unsure where the question might be. Any insights into this 502 behavior or steps I could take to debug further would be greatly appreciated! This is happening in both development and production on macOS.
