AJAX-HTTP-Error (TypeError) on export

I'm trying to export one of my content types with these field types:

• 1 file field (multi value)
• 1 links field (link module, multi value)
• 1 text field
• 1 paragraph reference with a text and an image field inside(paragraphs module, multi value)
• 1 taxonomy reference (multi value)

For the test I have only 3 nodes. Not all with data in links and file field, but all other fields are full filled.

This is my export config:

I uploaded screenshots too.

When I now start the export I get the following error:
