Hi @hhrutter,

My issue is based on the latest commit : https://github.com/pdfcpu/pdfcpu/releases/download/v0.4.1/pdfcpu_0.4.1_Windows_x86_64.zip

Os version :
Édition Windows 11 Professionnel
Version 22H2
Installé le ‎11/‎11/‎2022

I used a cerfa pdf, you can download it here : https://devsd.info/Arret_de_Travail_vierge.pdf
I would like to fill the form with the json then I export the JSON :
pdfcpu.exe form export Arret_de_Travail_vierge.pdf outfile.json
I add the values in the outfile.json everywhere.
Then I use the command to fill the form :
pdfcpu.exe form fill Arret_de_Travail_vierge.pdf outfile.json out.pdf
The following error is displayed :
writing out.pdf...
pdfcpu: textfield missing "DA"

out.pdf have a size of 0Kb then it's not working.

I don't have a form textfield named DA in the PDF file, I don't know what is this DA textfield.

Regards,

Sébastien.
