I tried to upgrade by installing 2.7.1.6 and after almost 24h, I have the following error :
PHP Fatal error: Call to a member function getId() on a non-object in /var/www/FengOffice/releases/2.7.1.6/public/upgrade/complete_migration.php on line 128
It just remains less that 900 objects on a total of almost 120.000 items and I can't finish the migration.
Afterinvestigating in the code and the database, it seems that there is no corresponding record on fo_project_tasks on the following request (called from $cobj = Objects::findObject($obj)

:
SELECT `id`, `object_type_id`, `name`, `created_on`, `created_by_id`, `updated_on`, `updated_by_id`, `trashed_on`, `trashed_by_id`, `archived_on`, `archived_by_id`, `object_id`, `parent_id`, `text`, `assigned_to_contact_id`, `completed_on`, `due_date`, `start_date`, `completed_by_id`, `order`, `milestone_id`, `started_on`, `priority`, `state`, `started_by_id`, `assigned_on`, `assigned_by_id`, `time_estimate`, `is_template`, `from_template_id`, `from_template_object_id`, `repeat_forever`,
`repeat_end`, `repeat_num`, `repeat_d`, `repeat_m`, `repeat_y`, `repeat_by`, `object_subtype`, `percent_completed`, `use_due_time`, `use_start_time`, `original_task_id`, `type_content`
FROM `fo_project_tasks` INNER JOIN `fo_objects` o
ON o.id = `fo_project_tasks`.object_id
WHERE `object_id` = '1446'
Do you have any idea on how to correct this ?
Thank you for your help,
fred
