I am trying to connect my app to DynamoDB. I have set everything up the way Amazon recommends. But i still keep getting the same error over and over again:

            What could be the solution?   

Answer 1

Okey it seems you need to add:

ddbClient.setRegion(Region.getRegion(Regions.EU_WEST_1));   // Add correct Region. In my case its EU_WEST_1 

after the following line:

AmazonDynamoDBClient ddbClient = new AmazonDynamoDBClient(credentialsProvider); 

Now it works. The table was successfully created. Have a nice day and thanks!

Answer 2

It seems that the table you are trying to connect to doesn't exist. Verify the table name in your code agains the name of the table you created.

Please note that table name is case sensative.
