Question
Can't generate QR code with Indesign Server

I use InDesign Server to generate previews and materials from my application. I have two scripts, first one to generate a preview (jpeg with watermark added) and material (pdf with pdfpreset). I use the same template file and the same datasource csv for each action. When I generate material QR codes are correctly generated, but for preview instead of QR codes I get gray boxes see attached file). How can I make it work?
I already contacted Robert at ID-Tasker, but I wanted to ask here since I have no working solution yet.
Indesign Server Version 20.0 x64 Windows Server 2022 Standard v. 21H2
