autoyast installation failing for SLES15 SP3 with error referring to multipath

This document (000020316) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 15 SP3
SUSE Linux Enterprise Desktop 15 SP3
SUSE Linux Enterprise Server for SAP 15 SP3
SUSE Manager Server 4.2

Situation

Autoyast installation is failing with the following error:

yast/wfm.rb(handle_exception):309 Internal error. Please report a bug report with logs.<br>Run save_y2logs to get complete logs.<br><br>Caller:  /mounts/mp_0001/usr/share/YaST2/lib/autoinstall/activate_callbacks.rb:34:in `multipath&#39;<br><br>Details: undefined method `fetch&#39; for &quot;&quot;:String

In the autoyast.xml there is the following entry in the general-section:

<storage/>

 

Resolution

Remove <storage/> from the autoyast.xml

Another solution would be to add:
<general>
<storage>
  <start_multipath config:type="boolean">false</start_multipath>
<storage>

Cause

Looking through the code it seems that the code can not handle when there is nothing specified. The fetch is not working on a empty or non-existing string. But the problem is that "yast clone_system" or in the menu "Miscellaneous |  Autoinstallation Cloning System" at <storage/>.

Another solution would be to add:

<general>
<storage>
  <start_multipath config:type="boolean">false</start_multipath>
<storage>
</general>
