AWS Transcribe is a powerful tool provided by Amazon Web Services that converts speech into text. It is widely used in applications that require voice recognition capabilities, such as transcription services, customer service automation, and more. AWS Transcribe is part of the broader suite of AWS AI services, which are designed to make it easier for developers to integrate machine learning capabilities into their applications.
When using AWS Transcribe, you might encounter an error message that reads: ExpiredTokenException. This error typically occurs when the security token included in your request has expired. As a result, your application may fail to authenticate with AWS services, leading to disruptions in service.
The ExpiredTokenException is an error code that indicates the security token used in your AWS request is no longer valid. AWS uses security tokens to authenticate requests and ensure that they are coming from authorized sources. These tokens have a limited lifespan, and once they expire, any requests made with them will be rejected.
Security tokens are designed to expire after a certain period to enhance security. This limits the window of opportunity for unauthorized access if a token is compromised. It is crucial to manage token lifecycles effectively to maintain seamless access to AWS services.
To resolve the ExpiredTokenException, you need to obtain a new security token and retry your request. Here are the steps to do so:
To obtain a new security token, you can use the AWS Security Token Service (STS). You can generate temporary security credentials using the GetSessionToken API. Here is an example of how to use the AWS CLI to get a new token:
aws sts get-session-token --duration-seconds 3600
This command will return a new set of temporary credentials, including an Access Key ID, Secret Access Key, and Session Token.
Once you have the new credentials, update your application to use these new values. Ensure that your application is configured to refresh these credentials periodically to avoid future token expiration issues.
After updating your application with the new credentials, retry the request that previously failed. If the new token is valid and correctly configured, the request should succeed.
