How To Perform Update On Dynamodb Local

Currently I have a local image of amazon/dynamodb-local . Whenever I try to perform an update operation on the database, it creates a duplicate row instead of updating the existing

Solution 1:

Just a latest development, yesterday I deleted the shared-local-instance.db and re intialized all the tables and everything was working fine. But today when i restarted everything, it is back to the same thing, The first image is when i perform the update now and the second is when i try to delete the duplicate record
