Since migrating our code to CIAM, we managed to connect to the API. However, we suddenly no longer are able to connect with the following error.

Thank you for reaching out to us.

It seems that you are still using the Version 1 Authentication code which requires a username, password, and client ID.

To use Version 2 Authentication (CIAM) which requires a client ID and client secret, you need to use RTSDK version 2.0.5 (EMA/ETA API version 3.6.5) and above.

The code looks like this:

OmmConsumer consumer = null;
 
AppClient appClient = new AppClient();
OmmConsumerConfig config = EmaFactory.createOmmConsumerConfig();
 
consumer = EmaFactory.createOmmConsumer(config.consumerName("Consumer_1").clientId(clientId).clientSecret(clientSecret));
 
consumer.registerClient(EmaFactory.createReqMsg().serviceName("ELEKTRON_DD").name(itemName), appClient);

For more information, please refer to the EMA Java API: Refinitiv Real-Time Optimized Version 2 Authentication Migration Guide article.

My code is exactly like this. However, you made me realize that the build did include 3.6.1. I will correct that and test again. Thanks

The issue was the packaging of the app. The wrong version of the ema libs were included. The code works with the right version now. Thanks!
