OCI-SDK Version Upgradation Issue v2.41.0 to v3.1.0

[ganeshshindegit]

Hi Team, For Helidon MP (2.5.4) microservice, I am not able to connect to the OCI vault after upgrading the OCI SDK version from 2.41.0 to 3.1.0, getting the exception Caused by: com.oracle.bmc.model.BmcException: Error returned by Unknown operation operation in Unknown service.(-1, null, false) Unknown error

Code Snippet for fetching the secretes from the OCI vault:

final InstancePrincipalsAuthenticationDetailsProvider provider = InstancePrincipalsAuthenticationDetailsProvider.builder().build();
            final Secrets secrets = SecretsClient.builder().build(provider);
            final SecretBundleContentDetails content = secrets.getSecretBundleByName(GetSecretBundleByNameRequest.builder()
                    .secretName(secreteName)
                    .vaultId(OCI_VAULT_ID)
                    .build())
                    .getSecretBundle()
                    .getSecretBundleContent();

I have attached the complete error stack trace file. I have also raised this topic on Oracle's internal slack channel.

There was a regression in Instance Principal auth in version 3.1.0 that was fixed in 3.2.0.

Please upgrade to version 3.2.1 or later.

Confirmed to work in 3.2.0 and higher.
