Import & OCR Rule doesn't seem to work

I have set up the “Import & OCR” Rule according top your [blog post][1], but it doesn’t seem to work: When I add scanned PDFs or images to the indexed folder ToDtk, they stay in there and no searchable PDF is created from it.

Here my the rules scxreen of the Smart Rule:

DEVONthink sees the incomning files, beacuse the are listed in the smart rule view:

but nothing happens with these two documents.

The way I understand the Smart Rule, I expect that an OCR-ed PDF is created and moved into the Inbox.

But when I for example search for name:Scan_2024-03-03-001 I only find the orginal PDF. Same is true for the image file.

What goes wrong here?
