Listing the objects in a S3 bucket in a Lambda Python function

I have many S3 issues, that is, accessing the S3 area via a Python Lambda function. Let me do something simple: List what objects are in a bucket.

From a new IAM account, newly created: S3 area:

• A bucket
• 2 objects (folders) in it
• One of them has 2 folders in it

The newly Lambda Python (from the new IAM account) is below. Original core from https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/s3.html

import json import boto3

session = boto3.Session( aws_access_key_id='ACCESS-KEY-HERE', aws_secret_access_key='SECRET-ACCESS-KEY')

def lambda_handler(event, context):

s3 = boto3.resource('s3')
bucket = s3.Bucket('dayones22')
for obj in bucket.objects.all():
    print(obj.key)
    
return {
    'statusCode': 200,
    'body': json.dumps('Hello from Lambda!')
}

IT NEVER EXECUTES. No coding errors are reported. Here’s what is…. EXECUTION RESULTS: Test Event Name TestPrintS3Tree67

Response { "errorMessage": "2024-02-26T17:14:30.738Z 2ddd5621-075e-4d9d-8772-34f1305908d9 Task timed out after 3.01 seconds" }

I have more Access issue, however, the most simply thing to do seems to be listing what is in the bucket.

HELP Please!
