Submissions don't appear after importing using Native XML Import v3.3.0.8 to 3.3.0.10

Hi,

I try to import an article from an OJS to another (v3.3.0.8 to v.3.3.0.10) using the Native XML Plugin, and it worked fine.
Then I went to the All actives and it says that I have a submission but it doesn’t show any submission at all.
We check the error logs and we got:

PHP Fatal error: Uncaught Error: Call to a member function getData() on null in /var/www/html/ojs/classes/search/ArticleSearchIndex.inc.php:38\nStack trace:\n

The print of what I’m seeing is

One of the reasons for this problem is deleting sections.

Are you sure you have the same “Sections” in both journals?
