Bug: Panic on asoctl import azure-resource with Role Assignment: Invalid Memory Address or Nil Pointer Dereference

[bertellil-prom]

Describe the bug

When attempting to import an Azure Role Assignment using asoctl import azure-resource, the command results in a panic with the following error:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x2 addr=0x30 pc=0x105b87a98]

Steps to Reproduce

1. Run the following command (Azure resource-specific details redacted for privacy):

   asoctl import azure-resource /subscriptions/<subscription-id>/providers/Microsoft.Authorization/roleAssignments/<role-assignment-id> --verbose

2. Observe the error logs, including the panic message.

Observed Behavior

The command fails and produces the following stack trace:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x2 addr=0x30 pc=0x105b87a98]

Expected Behavior

The resource import should complete successfully without any runtime errors.

Environment

• ASO Version: v2.11.0
• Command Used: asoctl import azure-resource
• Resource Details: Azure Role Assignment (specific details redacted)
• Azure Environment: Public Azure

Additional Information

• The issue appears to be linked to the RoleAssignmentExtension implementation at /workspace/v2/api/authorization/customizations/role_assignment_extensions.go:38.
• Similar issues may be occurring in the resource importer at /workspace/v2/cmd/asoctl/pkg/importresources.

[theunrepentantgeek]

Looks like I assumed a RoleAssignment would never be directly imported, only encountered as a resource extension when importing another resource - this would explain why the code assumes the owner value supplied to Import() is never nil. Should be a straightforward fix - and I'll check other implementations of Import() as well.
