Boto3 is the Amazon Web Services (AWS) Software Development Kit (SDK) for Python, allowing developers to write software that makes use of AWS services like S3, EC2, and DynamoDB. It provides an easy-to-use, object-oriented API, as well as low-level access to AWS services.
When using boto3 to interact with AWS services, you might encounter the InvalidUserId error. This error typically manifests when you attempt to perform operations that require a valid user ID, such as accessing resources or managing permissions.
The InvalidUserId error indicates that the user ID specified in your request is not recognized by AWS. This can happen if the user ID is mistyped, does not exist, or has been deleted. AWS requires valid user IDs to authenticate and authorize requests.
To resolve the InvalidUserId error, follow these steps:
Ensure that the user ID you are using is correct. You can verify the user ID in the AWS Management Console:
Review your IAM policies to ensure they reference the correct user ID:
If you are using a configuration file or environment variables to specify the user ID, make sure they are set correctly:
export AWS_ACCESS_KEY_ID="your_access_key_id"
export AWS_SECRET_ACCESS_KEY="your_secret_access_key"
