Hi,

I just updated to 9.1.2 to use the shinny new feature to check backup uploads and I it's not working for me.

 

I have tested it in PHP 8.3, 8.4 and 8.5 and also on PHP 7.4. For the latest I got this error:

 

Checking for failed uploads

* * * E R R O R * * *
1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''' AND `status` = 'complete' AND `type` != 'dbonly' AND `filesexist` = '1' AND `' at line 3 SQL=SELECT *
FROM `solo_ak_stats`
WHERE `profile_id` IN '' AND `status` = 'complete' AND `type` != 'dbonly' AND `filesexist` = '1' AND `remote_filename` EMPTY '' AND `backupstart` > '0000-00-00 00:00:00'
ORDER BY `id` DESC
/

 

For the PHP 8 versions I got this error:

 

You are using PHP 8.4.19 (cli)

Checking for failed uploads

* * * E R R O R * * *
0: mysqli_real_escape_string(): Argument #2 ($string) must be of type string, array given
/srv/users/carritos/apps/carritosbaratos/public/solo/vendor/akeeba/engine/engine/Driver/Mysqli.php:204
#

 

I think the issue is choosing the profile on the command, but I have tried adding --profile=2 but that changed nothing.

 

Best!!

Thank you for the detailed report. It was very helpful in tracking down the issue quickly.

The problem was in the backup engine's filter query builder. The new "check file upload" feature introduced two filter types (IN and EMPTY) that the query builder didn't know how to handle properly.

As for the different error messages, on PHP 8.x, this caused a type error because an array was passed where a string was expected. On PHP 7.4, the array silently converted to an empty string, producing invalid SQL.

The fix had already been applied to the backup engine, but it looks like I had forgotten to update it in the package. This is addressed now. The fix will definitely be included in the next release, planned for tomorrow.

Thank you again for taking the time to report this!
