Error: DynamoDB Errors InvalidSignatureException Signature Expired

Answered by Rafal Wilinski
What's Causing This Error
Signatures are only valid for a certain period. Sometimes, this error may arise because of the time difference between AWS time and your PC time.
Solution: Here's How To Resolve It
If you think the error is because of a time mismatch, check and confirm the time difference. If so, you can change your PC time to synchronize with the AWS time.
