keyword import does not work from PDF exported by Adobe InDesign

Hi,

I created a document with Adobe InDesign Cloud 2019 and added all kinds of metadata. I exported the document as PDF and when I import the PDF into TYPO3 the keywords are missing in the TYPO3 backend. Nothing gets imported.

When I edit the PDF with Adobe Acrobat the keywords are present so I wonder why it's not working with the exported InDesign file.

I use TYPO3 9.5.13.
