URL parameter concatenation without encoding could lead to injection issues. Use URL encoding for the deploymentId parameter.

initEnvConfig() is called before dataActor initialization. The dataActor variable is used inside initEnvConfig() but may not be initialized at this point in the main method.

Suggested change
public static void main(String[] args) {
public static void main(String[] args) {
// Initialize dataActor before calling initEnvConfig
dataActor = DataActorFactory.createDataActor();
