hi @mbuamuh

Would you simplify the SystemClient [getPropertiesHelper] method (

guide-cloud-aws/finish/inventory/src/main/java/io/openliberty/guides/inventory/client/SystemClient.java

Lines 67 to 87 in 7152dec

	/**
	* Helper method that processes the request
	* @param builder
	* @return
	*/
	protected Properties getPropertiesHelper(final Builder builder) {
	try {
	Response response = builder.get();
	if (response.getStatus() == Status.OK.getStatusCode()) {
	return response.readEntity(Properties.class);
	} else {
	System.err.println("Response Status is not OK.");
	}
	} catch (RuntimeException e) {
	System.err.println("Runtime exception: " + e.getMessage());
	} catch (Exception e) {
	System.err.println("Exception thrown while invoking the request: "
	+ e.getMessage());
	}
	return null;
	}

) as this getPropertiesHelper? and update the class under the start directory, and verify it on AWS again?
