ListInstances method SSO on AWS API differ from AWS CLI

[cpfarher]

I'm trying to get sso instances with the api described here: https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/clients/client-sso-admin/index.html without success.

For that I write something like this:

import {ListInstancesCommand, SSOAdminClient} from '@aws-sdk/client-sso-admin';
const client = new SSOAdminClient({credentials: {accessKeyId: 'foo', secretAccessKey: 'bar'}, region: 'us-east-2'});
const response = await client.send(new ListInstancesCommand({MaxResults: 100}))

That code returns a success response(200) but the instance object was undefined. This is the dump of response:

{"$metadata": 
              {
               "httpStatusCode":200,
               "requestId":"7a87a1a7-d0f8-4a79-be2c-0aa9c179bdac",
               "attempts":1,
               "totalRetryDelay":0
              },
 "Instances": undefined,
 "NextToken": undefined
}

While, If I use exactly the same keys on de CLI it works and I got 1 instance:

aws sso-admin list-instances --max-items 100

The response:

{
    "Instances": [
        {
            "InstanceArn": "arn:aws:sso:::instance/ssoins-6684c191c332b481",
            "IdentityStoreId": "d-9a6710feea"
        }
    ]
}

Any idea why I got different results? Thanks!

I discover a monkey patch in our app that brokes the response!.
