Exception in thread "main" com.oracle.bmc.model.BmcException: (404, NamespaceNotFound, false)

Question

I executed the OCI sample program ObjectStorageGetBucketExample.java and was able to create the bucket and add the file. But, when I ran the ObjectStorageAsyncExample.java and ObjectStorageSyncExample.java to list the bucket. I got the following errors:

Exception in thread "main" com.oracle.bmc.model.BmcException: (404, NamespaceNotFound, false) You do not have the authorization to perform this request, or the requested resource could not be found.

I can write but can't read. I just want to know what type of authorization do I need?

Here is the full errors:

Answer 1

It looks as though it is attempting to list buckets. The ListBuckets operation requires BUCKET_INSPECT permission.

https://docs.cloud.oracle.com/en-us/iaas/Content/Identity/Reference/objectstoragepolicyreference.htm

Permissions are granted via IAM policies. And BUCKET_INSPECT can be granted explicitly, but is also included in inspect buckets and inspect object-family.

hope this helps!
