Anyone here used the DynamoDB SQL Connector with

ASSUME_ROLE

credentials? I tried running a very simple

CREATE TABLE

and

INSERT

statement but i get an error related to the credentials. The jar connector is already in the

lib

directory. I tried to do some sanity check and used the aws cli to assume-role and I was able to read and write to the DynamoDB table. What could be the problem here?

Copy code

Caused by: software.amazon.awssdk.services.sts.model.StsException: 2 validation errors detected: Value null at 'roleArn' failed to satisfy constraint: Member must not be null; Value null at 'roleSessionName' failed to satisfy constraint: Member must not be null

Hi, do you see the same error if you remove

aws.credentials.role.provider

parameter?

Currently you specifying

ASSUME_ROLE

as nested credentials provider for

ASSUME_ROLE

provider. If you need this nesting, then you’ll need to also specify parameters for your nested provider, e.g.:

Copy code

'aws.credentials.provider' = 'ASSUME_ROLE',
  'aws.credentials.role.arn' = 'arn:aws:iam:111111111111:role/dummyRole',
  'aws.credentials.sessionName' = 'dummy-session_1',
  'aws.credentials.role.provider' = 'ASSUME_ROLE',
  'aws.credentials.role.provider.role.arn' = 'arn:aws:iam:222222222222:role/dummyRole',
  'aws.credentials.role.provider.role.sessionName' = 'dummy-session_2'
