Does not work backup and restore in Teampass 3.1.2

[margeu]

After Backup, if I try to Restore getting the following error in red alert:

Error caught
An error appears. Answer from Server cannot be parsed!
Returned data:
true

The only error I detect connected to the restore function is in the log /var/log/php-fpm/www-error.log with the following message

[06-Mar-2024 16:59:43 UTC] /tmp/phpGng0R2
[06-Mar-2024 16:59:46 UTC] PHP Warning: Undefined array key "post_totalSize" in /var/www/html/TeamPass/sources/backups.queries.php on line 292

The configuration is:
Web server: httpd-2.4.57
Database: mariadb 10.5.22
PHP version: PHP 8.1
Operating system: RHEL 9.3

Has anyone successfully tried backup and restore with version 3.1.2 ?

Thank you for your feedback
