Generate reports on due date doesn't return any similarity score

[gbarat87]

Hi,
In assignment with plagiarism_turnitin activated, when you set up the settings for "Report Generation Speed" => "Generate reports on due date (students can resubmit until due date)" We can't get the similarity report back to moodle.
It works fine with other settings. But this one doesn't return any score.
Due has passed, the corresponding cron has been triggered (plagiarism_turnitin\task\update_reports )

• File updated : xxxxx
• Scheduled task complete

And no score are showing up.
I have checked the APIlog, and there is no score in the tree for this assignment.

The only error I could find so far is in the turnitin report itself
"The Similarity service is not available for this paper.
A problem occurred when processing the application URL."
