@Marvin I followed the instructions for loading aws credentials but when I try to upload a file to s3 I get a NoCredentialsError: Unable to locate credentials message. If I try to load the credentials again prefect tells me I'm overwriting the credentials. Why would this happen?

It appears you're having some trouble with AWS credentials in Prefect. From the information I could find, it seems that when setting up your environment for AWS, you need to provide programmatic access with proper IAM user credentials. This usually involves creating an AWS IAM user and setting up a credentials file on your local system or in the environment where Prefect is running. The

NoCredentialsError

suggests that the AWS credentials Prefect is trying to use aren't found. If Prefect notifies you that you're overwriting credentials when you try loading them again, this could mean that the credentials are already present in the environment but are perhaps not correctly configured or not accessible due to file permissions or environment variable settings. Since there were no open issues found regarding the

NoCredentialsError

on the Prefect GitHub Issues, it might be a specific setup issue on your end. Check the following: 1. Ensure the AWS credentials file is correctly formatted and located in the default directory (

~/.aws/credentials

for Unix-like systems or

C:\Users\USERNAME\.aws\credentials

for Windows) or the location you specified. 2. Confirm that the environment variables

AWS_ACCESS_KEY_ID

and

AWS_SECRET_ACCESS_KEY

are set if you're not using the credentials file. 3. Check that the IAM user has the correct permissions to perform S3 operations and that the credentials are active. 4. Make sure that the region is specified if it's required for S3 operations. Without specifics on how you're loading the credentials or the code, I can't do more than speculate. But I hope this general advice helps you to find the issue. If the problem persists, double-checking the Prefect documentation or seeking support from the Prefect community could prove fruitful.
