When the viewer is executed the next exception happen:

❯ java -jar viewer/target/viewer-1.0.jar 
Exception in thread "main" java.lang.NullPointerException
        at java.base/java.util.concurrent.ConcurrentHashMap.putVal(ConcurrentHashMap.java:1011)

        at com.redhat.telemetry.viewer.ConsumerApp.configureProperties(ConsumerApp.java:28)
        at com.redhat.telemetry.viewer.ConsumerApp.main(ConsumerApp.java:38)

This error happens because the ConsumerApp class is getting configuration from the Producer Properties not setted.

The following properties don't exist in the ProducerProperties class:

• SslConfigs.SSL_KEYSTORE_LOCATION_CONFIG
• SslConfigs.SSL_KEYSTORE_PASSWORD_CONFIG

Quarkus released the new 2 version with several improvements and features. As these exercises are defined to understand better how to implement EDA applications, with Java plain or Quarkus, both cases should be using the latest versions.

This enhacement is to upgrade the current exercises to the latest version of Quarkus (currently 2.0.2.Final). This new version will provide to the student the best development lifecycle and make him/her more happy 😄.

Hi,

When I got to this step:
lab start eda-setup

I get this error:
File "/Users/XXXX/AD482/.venv/lib/python3.8/site-packages/ocpcli/client.py", line 160, in apply_template
with open(template_path) as template_file:
FileNotFoundError: [Errno 2] No such file or directory: '/Users/XXXX/AD482/.venv/lib/python3.8/site-packages/ad482/common/kubefiles/templates/cluster.yaml'

Can you please assist ?

I am doing the AD482 course, and I am not able to run correctly some of the labs. Currently I am working on the "Guided Exercise: Processing Data Streams". I notice that in the application.properties some properties are unknown, and therefore when running the application I cannot connect to the bootstrap server.

The properties are :
kafka.security.protocol = SSL
kafka.ssl.truststore.location = /AbsolutePath/truststore.jks
kafka.ssl.truststore.password = password

I had issues with the other labs as well, but to overcome it I deployed the app in the cluster and removed these properties.

Would be great if you could have a look at this.

Best,

Etienne.

Hi,

I'm using a MacOS Monterey with M1 chip.

The application runs up, but is rising errors related to RocksDB
