Unable to add disk to Panorama from API / SDK

[APalermo865634]

Im unable to add disks attached to my Panorama instance from the xml api.
I used the provided request from the xml api browser

<request><system><disk><add>sdd</add></disk></system></request>

I tried the same from the Python SDK using the "op" function
also tried Ansible using the op command as well.
None worked all return the same issue:

<response status="error">
    <msg>
        <line>An error occured. See dagger.log for information.</line>
    </msg>
</response>

From reading dagger.log i can get only this

2024-11-20 07:19:14.347 -0800 OPCMD: handler "panlogs_vld_mgr_handler.add"
2024-11-20 07:19:14.347 -0800 Error:  dag_pyif_call_method(dagger_pyif.c:260): Method not found (add_xml)

------

I tried adding them manually from the CLI using:

request system disk add sdd

and it worked successfully, but I need to have this step automated for future deploys.

Am I missing something here thats causing the error?? has anyone encounter anything similar ?
