When i try to run into my local computer work correctly, but when i move into Windows server 2021 THere is error code

  File "C:\Users\loc\AppData\Local\Programs\Python\Python39\lib\site-packages\botocore\auth.py", line 357, in add_auth
    raise NoCredentialsError
botocore.exceptions.NoCredentialsError: Unable to locate credentials

What is problem? Credentials is 100% correct, because as I told it's work in my local computer. I mean, when i run in my Computer, Windows 10 it's works correctly, when i run another computer, Windows 2012 server not works

Answer 1

Though you provided credentials in code, you are not using it anywhere.

It works in your local machine because, you might have AWS CLI installed and configured credentials and the code would have used that configured creds

The below code will use inline creds in code, however would advice you to use creds set using EC2 instance profile deployed to AWS or use configured creds with CLI

import boto3
session = boto3.Session(
    aws_access_key_id=access_key,
    aws_secret_access_key=access_secret
)

 s3_resource = session.resource("s3", region_name="eu-west-2")
