Today, after having upgraded to nextcloud 25.0.2 about 2 days ago, i received an E-mail from the next cloud cron job:
TypeError: Cannot access offset of type string on string in /home/nextcloud/httpd/www/html/nextcloud/apps/theming/lib/Jobs/MigrateBackgroundImages.php:74

Nextcloud version: 25.0.2
Operating system and version: Fedora 37
Apache or nginx version: 2.4.54
PHP version: 8.1.13
The issue you are facing:
I received the mail noted down above. Don’t know, if the job failed. When i run it manually, i get no error message. Probably it happened only one time after the upgrade of nextcloud to 25.0.2 ? But since the upgrade this cron job has run a lot of times already without emitting the error.
Is this the first time you’ve seen this error? (Y/N): yes
Steps to replicate it:
- Upgrade to nextcloud 25.0.2
- let the cron job run several times (don’t know, how often is required), don’t know if this will ever happen again

The output of your Apache/nginx/system log in /var/log/____:
there is no output caused by this cron job.
Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.
no output has been caused by this cron job, all i have is the content of the mail (see above)
Around line 74 of MigrateBackgroundImages.php i see:
protected function run($argument): void {
if (!isset($argument[‘stage’])) {
// not executed in 25.0.0?!
$argument[‘stage’] = self::STAGE_PREPARE;
}
Frankly i do not have sufficient insight and overview. Could it be
the run method is called with an uninitialized argument ? Then it might help to assign an empty array as default like this:
protected function run($argument = ): void {
Following up the stack trace and looking at /lib/public/BackgroundJob/Job.php
abstract class Job implements IJob {
protected int $id = 0;
protected int $lastRun = 0;
protected $argument;
there is no default value. Unless the method setArgument is called, $argument remains unset. Could this be the issue ?
Someone else reported an error in the logs and webdav being broken. It might be the same. Thank you for helping.
