AWS Lambda Function scenarios with 'Task timed out after 3.00 seconds' scenarios Despite Sufficient Timeout Setting
I'm working on a personal project and I've encountered a strange issue with I'm working on a personal project and This might be a silly question, but This might be a silly question, but I am working with a frustrating scenario with my AWS Lambda function that is timing out after 3 seconds, even though I have configured the timeout to be 30 seconds... The Lambda function is supposed to process a large batch of records from DynamoDB and send them to an SQS queue. The behavior message I receive in the AWS Lambda console is: `Task timed out after 3.00 seconds`. I've checked my settings multiple times and even increased the memory allocation in case it was a performance scenario. Here’s the relevant part of my Lambda function: ```python import boto3 import json import os dynamodb = boto3.resource('dynamodb') sqs = boto3.client('sqs') def lambda_handler(event, context): table = dynamodb.Table(os.environ['DYNAMO_TABLE']) response = table.scan() for item in response['Items']: # Simulate processing time process_item(item) # Send to SQS queue sqs.send_message( QueueUrl=os.environ['SQS_QUEUE_URL'], MessageBody=json.dumps(item) ) return {'statusCode': 200, 'body': 'Processed items'} def process_item(item): # Simulate a processing delay import time time.sleep(5) # This simulates heavy processing ``` I've set the timeout to 30 seconds in the Lambda configuration and I see that it is correctly set in the AWS Management Console. However, it seems the function is always timing out at 3 seconds, which is the default timeout setting. I've also tried deploying the function using the AWS CLI with the following command: ```bash aws lambda update-function-configuration --function-name myLambdaFunction --timeout 30 ``` I’ve verified that the environment variables for both `DYNAMO_TABLE` and `SQS_QUEUE_URL` are set correctly. Has anyone else experienced this scenario? Is there a specific configuration I might be missing that would cause the Lambda function to revert to the default timeout setting? Any help would be greatly appreciated! My team is using Python for this application. Am I missing something obvious? This issue appeared after updating to Python LTS. How would you solve this?
