@Marvin I am trying to deploy some flows and I am getting the following error PermissionError: The AWS Access Key Id you provided does not exist in our records What could be the cause?

The error message "The AWS Access Key Id you provided does not exist in our records" typically suggests one of the following issues: 1. Incorrect AWS Credentials: The AWS access key ID or secret access key might be wrong. Double-check that the credentials are correctly set and match what is in AWS IAM. 2. Environment Variables: Ensure that your environment variables for AWS credentials are correctly set. You might be missing the

AWS_ACCESS_KEY_ID

or

AWS_SECRET_ACCESS_KEY

environment variables. 3. IAM Policies and Permissions: Verify that the AWS credentials you are using have the correct permissions to perform the required operations. You might need to check the IAM policies attached to the credentials. 4. AWS Session Token: If you're using temporary security credentials, make sure the

AWS_SESSION_TOKEN

is also set correctly. These points are reflected in a GitHub issue that was found related to a similar problem: Auth error when registering a flow with s3 storage. Here's a summary of what you can try: 1. Double-check Credentials: Ensure that your AWS credentials are correct and reflected in your environment variables.

bash
   export AWS_ACCESS_KEY_ID=your_access_key_id
   export AWS_SECRET_ACCESS_KEY=your_secret_access_key
   export AWS_SESSION_TOKEN=your_session_token  # if using temporary credentials

2. Verify Using boto3 Directly: Try listing your S3 buckets using

boto3

directly to ensure that your credentials are correct.

python
   import boto3

   s3 = boto3.resource("s3")
   for bucket in s3.buckets.all():
       print(bucket.name)

3. Check IAM Policies: Make sure the user or role associated with the credentials has the necessary permissions. If these steps do not resolve your issue, then providing more context on how you are configuring your Prefect flow and specifying your Prefect version might help further diagnose the problem.
