Endless loading / error in user's notifications / tasks

That’s this line:

pkp/pkp-lib/blob/stable-3_3_0/controllers/grid/notifications/NotificationsGridCellProvider.inc.php#L157


      
          		if (!isset($submissionId) && isset($fileId)) {
          			assert(is_numeric($fileId));
          			$submissionFile = Services::get('submissionFile')->get($fileId);
          			assert(is_a($submissionFile, 'SubmissionFile'));
          			$submissionId = $submissionFile->getData('submissionId');
          		}
          		assert(is_numeric($submissionId));
          		$submission = Services::get('submission')->get($submissionId);
          		assert(is_a($submission, 'Submission'));
          
          		return $submission->getLocalizedTitle();
          	}
          }

So that means it is trying to find a notification for a submission or submission file that doesn’t exist in the database. You’ll want to add an entry to your error log to identify the submission ID or submission file ID that is causing the problem:

// Add this just above line 157
if (is_null($submission)) {
    error_log($submissionId . '/' . $fileId);
}
