I have an error restoring a backup.(error/cannot precheck_wrong_status)

I check the script in restore_includes.php :

// Schema Restore backup into course.
            $controller = new restore_controller($folder, $course_id, backup::INTERACTIVE_NO, backup::MODE_SAMESITE, $userdoingrestore, backup::TARGET_NEW_COURSE);
              
            //error when execute_precheck
            $controller->execute_precheck();
           
            $controller->execute_plan();
            $transaction->allow_commit();
            // end Schema Restore backup into course.
           
            //print_r($folder, $course_id); //die();

I attached the screenshoot and file backup.mbz

Could you turn debugging on and see if you get a more detailed error?

Me thinks you have a role in the backup file causing the issue +  a non-interactive setting?

So do this:

Extract your backup.mbz

tar zxvf backup.mbz

edit moodle_backup.xml file

Change the following:
<name>role_assignments</name>
Value set to 0 ... not 1.

<interactive></interactive>

Set to 1:
<interactive>1</interactive>

re-package the .mbz

tar -czvf backup.mbz *

When restoring and you get to the interactive part, make sure
you do NOT restore roles ... un-check if there is a box for you to decide.

Resorting a course that might have an admin account level in it conflicts
with admin users already in the system.

Might consider creating backups with no roles in future ... especially IF you
have an admin level user in a course.  You can always re-assign roles to the course.

BTW, tested this on a 2.8.highest version of Moodle and it failed the first time ... almost right off the bat.   The suggested error link didn't mention specifics enough.    So I inspected and compared a valid/working .mbz backup to yours.

After making the changes to the moodle_backup.xml file above, restored without issue ... **did un-check option to restore roles on my system** ... for obvious reasons.

Dear Ken and Emma,

Thank you for your respons

actually I made Aplication that execute moodle core. The Aplication run to make a backup.mbz from course in LMS Server and then restore it to LMS Client.

The backup.mbz file succesfull create in temp but when restoring i got error precheck status

Already set debug on in config file

@ini_set('display_errors', '1');
$CFG->debug = 38911;
$CFG->debugdisplay = true;

Welcome.  Interesting.   All I can tell ya I've said in the previous response - making edits to the backup's moodle_backup.xml file  shared with you, the course restored without the error you are seeing.

Since this is really an app/addon you've programmed might I suggest moderator move this to the forum for developers cause I think this is a development question.
