Error: com amazonaws services dynamodbv2 model resourcenotfoundexception

What's Causing This Error

This error occurs in Java when you try to access a DynamoDB Table, GSI, or LSI that does not exist or is still in the "CREATING" status.

Solution - Here's How To Resolve It

First, verify that the region you've specified when initializing the SDK is the same region in which the DynamoDB tables are provisioned.

Then, verify that the table, LSI, or GSI name you are trying to access is correct.

Finally, visit the AWS Console to determine if the table is in the "Active" status. If your table has been created, you should see the status below.
