standalone nsfs: process getting crashed when we hit anonymous tests

[vh05]

Process getting crashed when we trigger anonumous object operations. I think the error handling at object_sdk.js i.e

throw new RpcError(......); needs to be checked.

When we run

s3tests_boto3/functional/test_s3.py::test_bucket_list_objects_anonymous_fail s3tests_boto3/functional/test_s3.py::test_bucket_listv2_objects_anonymous_fail
