AWS DynamoDB resource not found exception

Question

I have a problem with connection to DynamoDB. I get this exception:

com.amazonaws.services.dynamodb.model.ResourceNotFoundException: Requested resource not found (Service: AmazonDynamoDB; Status Code: 400; Error Code: ResourceNotFoundException; Request ID: ..

But I have a table and region is correct.

Answer 1

From the docs it's either you don't have a Table with that name or it is in CREATING status.

I would double check to verify that the table does in fact exist, in the correct region, and you're using an access key that can reach it

Answer 2

If DynamoDB table is in a different region, make sure to set it before initialising the DynamoDB by

AWS.config.update({region: "your-dynamoDB-region" });

This works for me:)

Answer 3

My problem was stupid but maybe someone has the same... I changed recently the default credentials of aws (~/.aws/credentials), I was testing in another account and forgot to rollback the values to the regular account.

Answer 4

Always ensure that you do one of the following:

1. The right default region is set up in the AWS CLI configuration files on all the servers, development machines that you are working on.
2. The best choice is to always specify these constants explicitly in a separate class/config in your project. Always import this in code and use it in the boto3 calls. This will provide flexibility if you were to add or change based on the enterprise requirements.

Answer 5

If your resources are like mine and all over the place, you can define the region_name when you're creating the resource.

I do this for all my instantiations as it forces me to think about what I'm putting/calling where.

boto3.resource("dynamodb", region_name='us-east-2')
