AWS Kinesis is a platform on AWS to collect, process, and analyze real-time, streaming data. It allows developers to build applications that can continuously ingest and process large streams of data records in real-time. Kinesis is commonly used for log and event data collection, real-time analytics, and more.
When interacting with AWS Kinesis, you might encounter the RequestExpired error. This error typically manifests when a request is made to the Kinesis service, but the request timestamp is considered too old by AWS standards.
The RequestExpired error occurs when the request's timestamp is older than 15 minutes from the time it reaches AWS. This is often due to the system clock being out of sync with the AWS server time. AWS uses Coordinated Universal Time (UTC) for all timestamps, and any significant deviation can lead to this error.
The primary cause of this issue is an unsynchronized system clock. If your system's time is not aligned with the AWS server time, AWS will reject the request as expired.
To resolve the RequestExpired error, follow these steps:
Ensure that your system clock is synchronized with a reliable time source. On Linux systems, you can use the Network Time Protocol (NTP) to keep your system time accurate. Install and start the NTP service using the following commands:
sudo apt-get update
sudo apt-get install ntp
sudo service ntp start
For Windows systems, ensure that the Windows Time service is enabled and configured to synchronize with an internet time server.
After setting up NTP, verify that your system time is synchronized. You can check the current time and date using the date command on Linux or by checking the Date and Time settings on Windows.
Once your system clock is synchronized, retry the request to AWS Kinesis. Ensure that the request is sent promptly to avoid any further expiration issues.

By ensuring your system clock is synchronized and requests are sent promptly, you can effectively resolve the RequestExpired error and maintain seamless interaction with AWS Kinesis.
