No link to file download after batch finished

It works for me with batch export... I see the download link after.

Maybe this is your issue?

🐛 Batch redirect fails for views with path parameters Needs work

Upgraded to the dev version. No parameters in view or export link path. All kinds of config parameter combination. Still no download link after the batch finishes :-(

Could you perhaps post a screenshot so that I at least know where to look for the download link?

It's a system info message, such as would show by calling

\Drupal::messenger()->addMessage($message);

which it does call. See DataExport.php, line 911.

Thanks solidegloria, thanks to you I've realized my "Status messages" block newer displayed.

The reason has something to do with BigPipe module, see https://stackoverflow.com/questions/66011876/drupal-9-message-and-messag...

Created a core issue to examine the problem: https://www.drupal.org/project/drupal/issues/3341735 💬 Status messages block not showing while BigPipe module enabled in contrib/custom admin theme Postponed: needs info

But this ticket can now close as there's no problem with views_data_export ✓
