Target is missing error on Drupal 9

I am trying to use the Feeds Paragraph module on a Drupal 9 installations.
I added both patches ( https://www.drupal.org/project/feeds_para_mapper/issues/3147462 📌 Automated Drupal 9 compatibility fixes Needs review and https://www.drupal.org/project/feeds_para_mapper/issues/3177019 🐛 Compatibility problems caused by feeds update Fixed ) but it doesn't work correctly.

When I add a paragraph field without the Feeds Paragraphs module enabled, the mapper settings allow me to choose the paragraph type, but no fields are displayed or can be selected. I am not sure if this is common behavior or already an issue with either Paragraphs or the Feeds module. But the interface works correctly and the settings stay.

After enabling the Feeds Paragraphs module, after saving the mapping I get the error: "Error: Target is missing"

I also get 3 different error in the logs:
