Calling YaST module has failed

[ElBarto]

Hello,
On OpenSUSE Tumbleweed 15.6, I installed autoyast2 to generate
an autoinst.xml file and then integrate it into the openSUSE ISO to
automate its installation.
I managed to create the file, judged correct and logical by Yast,
I copied it into the directory of my unzipped iso, modified
grub.cfg to indicate the file, in this way:
autoyast=file:///PATH/TO/autoinst.xml
then I reformatted the ISO with mksusecd.
The file is detected but the installer reports errors:
Calling YaST module inst_autoinit has failed.
More information can be found near the end of the /var/log/YaST2/y2log file
Calling YaST module inst_autosetup has failed.
More information can be found near the end of the /var/log/YaST2/y2log file
I tried to create a file to clone the machine, but same problem,
the YaST modules do not load.
Is there an argument to add in grub.cfg to launch these modules?
Thanks to those who can help me.

I was able to fix the module loading problem:
After examining the files included in the ISO, I found a file
control.xml (boot\x86_64) in which I modified these parameters:
<rle_offer_rulevel_4 config:type=“boolean”>true</rle_offer_rulevel_4>
by default the value is false,
then in
I modified these parameters:
AutoYaST Settings
initial_update_proposal
inst_proposal
initial
<enable_back>yes</enable_back> (defaults to no)
<enable_next>yes</enable_next>
And now the YaST modules are running!
But I need to review the installation of the desktop and add-ons:
currently the installer does not provide a desktop and reports
errors regarding access to add-ons…
If someone can enlighten me, here is the file used:

autoinst.xml
