Amazon Simple Storage Service (S3) is a scalable object storage service provided by AWS. It is designed to store and retrieve any amount of data from anywhere on the web. S3 is commonly used for backup and archiving, content storage and distribution, and data lakes.
When interacting with Amazon S3, you might encounter the TokenRefreshRequired error. This error typically manifests when an application or user attempts to access S3 resources and the authentication token used is no longer valid.
The TokenRefreshRequired error occurs when the temporary security credentials used to authenticate requests to S3 have expired. AWS uses temporary credentials to enhance security by limiting the duration of access. These credentials include an access key ID, a secret access key, and a session token.
Temporary credentials are issued with a limited lifespan to reduce the risk of unauthorized access. Once expired, any attempt to use them will result in a TokenRefreshRequired error.
To resolve this issue, you need to refresh the token and retry the request. Here are the steps to do so:
Use the AWS Security Token Service (STS) to obtain new temporary credentials. You can do this using the AWS CLI:
aws sts assume-role --role-arn "arn:aws:iam::123456789012:role/example-role" --role-session-name "example-session"
This command will return a new set of temporary credentials.
Replace the expired credentials in your application or environment with the new credentials obtained from the previous step. Ensure that the access key ID, secret access key, and session token are updated.
Once the credentials are updated, retry the request to access the S3 resources. The request should now succeed if the credentials are correctly refreshed.
