I'm having problems when restoring a backup. In debug the following error appears:

Debug info: Unknown column 't.entrytext' in 'field list'
SELECT t.id, t.entrytext, t.exittext
FROM mdl_taskchain t
Mdl_backup_ids_temp JOIN b ON t.id = b.newitemid
WHERE b.backupid =?
AND b.itemname =?
[array (
0 => '590a826a0e20cbf2bb6a96072b56a49a '
1 => 'taskchain'
)]
Error code: dmlreadexception
