Hi,
the CrossRef XML Export Plugin is not displaying the articles.
The following error is appearing in the log:
ror] [pid 13360] [client 172.20.7.116:55065] PHP Fatal error: Uncaught Error: Call to a member function getId() on null in /var/www/ojs-3.2.1-1/controllers/grid/submissions/ExportPublishedSubmissionsListGridCellProvider.inc.php:77\nStack trace:\n#0 /var/www/ojs-3.2.1-1/lib/pkp/classes/controllers/grid/GridCellProvider.inc.php(56): ExportPublishedSubmissionsListGridCellProvider->getCellActions(Object(Request), Object(GridRow), Object(GridColumn))\n#1 /var/www/ojs-3.2.1-1/lib/pkp/classes/controllers/grid/GridHandler.inc.php(1104): GridCellProvider->render(Object(Request), Object(GridRow), Object(GridColumn))\n#2 /var/www/ojs-3.2.1-1/lib/pkp/classes/controllers/grid/GridHandler.inc.php(1011): GridHandler->_renderCellInternally(Object(Request), Object(GridRow), Object(GridColumn))\n#3 /var/www/ojs-3.2.1-1/lib/pkp/classes/controllers/grid/GridHandler.inc.php(988): GridHandler->renderRowInternally(Object(Request), Object(GridRow))\n#4 /var/www/ojs-3.2.1-1/lib/pkp/classes/controllers/grid/GridHandler.inc.php(1033): GridHandler->renderRowsInternally(Object(Request), Array)\n#5 /var/ww in /var/www/ojs-3.2.1-1/controllers/grid/submissions/ExportPublishedSubmissionsListGridCellProvider.inc.php on line 77, referer: https://periodicos.ufes.br/romanitas/management/importexport/plugin/CrossRefExportPlugin
What could it be? In some other journals, it does not display any articles and in others it works normally. In this one, it keeps charging all the time.
