how to Retrieve OCI Resource Metadata Using Java SDK - Missing Attributes scenarios
I'm not sure how to approach I'm trying to retrieve metadata for a specific resource in my Oracle Cloud Infrastructure (OCI) account using the Java SDK version 2.15.0, but I'm running into an scenario where essential attributes seem to be missing in the response. After successfully authenticating and setting up the client, my code looks like this: ```java import com.oracle.bmc.auth.SimpleAuthenticationDetailsProvider; import com.oracle.bmc.core.VirtualNetworkClient; import com.oracle.bmc.core.model.GetVcnRequest; import com.oracle.bmc.core.model.Vcn; public class OciMetadataFetcher { public static void main(String[] args) throws Exception { SimpleAuthenticationDetailsProvider provider = SimpleAuthenticationDetailsProvider.builder() .tenantId("<TENANT_ID>") .userId("<USER_ID>") .fingerprint("<FINGERPRINT>") .privateKeySupplier(() -> new FileInputStream("<PATH_TO_PRIVATE_KEY>")) .build(); VirtualNetworkClient vnClient = VirtualNetworkClient.builder() .build(provider); GetVcnRequest request = GetVcnRequest.builder() .vcnId("<VCN_ID>") .build(); Vcn response = vnClient.getVcn(request).getVcn(); System.out.println("VCN Name: " + response.getDisplayName()); System.out.println("VCN CIDR: " + response.getCidrBlock()); // Trying to access a missing attribute System.out.println("VCN Lifecycle State: " + response.getLifecycleState()); } } ``` When I run this code, I get this output: ``` VCN Name: MyVcn VCN CIDR: 10.0.0.0/16 VCN Lifecycle State: null ``` I expected the lifecycle state to be either "ACTIVE" or "TERMINATED", but it's returning null. I've checked the OCI console, and the VCN is indeed active. I've also ensured that my IAM policies are correctly set up to allow read access to the VCN resource. To troubleshoot, I tried fetching other attributes, like `getDefinedTags()`, which also returns null. I verified that my SDK is up to date and that there's no version mismatch with the API. Is there a specific configuration or setting that I might be missing? Has anyone else experienced similar issues with missing attributes when using the OCI Java SDK?
