How do i get the list of objects in S3 having Key Error and exceptions

I am new to this AWS boto3 concepts .The below code is giving a Key error  and some exception  that i am trying to execute can someone look to it and try to solve if any errors?

import boto3

def list_s3_objects(bucket_name):
    s3 = boto3.client('s3')
    objects = []
    try:
        response = s3.list_objects_v2(Bucket=bucket_name)
        for obj in response['Contents']:
            objects.append(obj['Key'])
    except Exception as e:
        print(f"An error occurred in the following ie,: {e}")
    return objects

def main():
    bucket_name = 'name of my bucket'
    objects = list_s3_objects(bucket_name)
    print("S3 Objects to be created are:")
    for obj in objects:
        print(obj)

if __name__ == "__main__":
    main()

I tried different excepts to handle and even my login details were correct . But it also showed as key error . I just wanted to print my s3 bucket objects .

>Solution :

The below code lists the s3 objects as you have specified. Here I have added the paginator and botocore.exceptions for checking exception.  Thank you

import boto3
from botocore.exceptions import ClientError

def list_s3_objects(bucket_name):
    s3 = boto3.client('s3')
    objects = []
    try:
        paginator = s3.get_paginator('list_objects_v2')
        for page in paginator.paginate(Bucket=bucket_name):
            if 'Contents' in page:
                for obj in page['Contents']:
                    objects.append(obj['Key'])
    except ClientError as e:
        print(f"Error occurred is: {e}")
    return objects

def main():
    bucket_name = 'my-bucket'
    objects = list_s3_objects(bucket_name)
    print("S3 Objects are :")
    for obj in objects:
        print(obj)

if __name__ == "__main__":
    main()
