Heeelp! I'm stuck... Girl is freakin' here :(

ou do not appear to be calling lambda_handler anywhere in your code

obviously the whole if block is part of the function - e.g. it uses event

Ahh, that changes the code a bit more then

import boto3
def lambda_handler(event, context):
    s3 = boto3.client("s3")
  
    if event:
        print("Event : ", event)
        file_obj = event["Records"][0]
        filename = str(file_obj['s3']['object']['key'])
        print("Filename: " , filename)
        fileObj = s3.get_object(Bucket = "chargifytesting" , Key=filename)
        file_content = fileObj["Body"].read().decode('utf-8')
        print(file_content)
