[PDFSharp - Fillable PDF] Error when calling action FormFields_Get: "Internal Error: Internal trace failure: ."

Service Studio Version

Platform Version

I'm getting this error when after uploading a file and clicking the button 'GetFields'.

Any idea why this error occurs?

Context: For a customer I am replacing a document with a newer version. For the old version, this action is still working. But for the new version, I get this error. So the error depends on which document is being processed. Unfortunately I cannot share the documents.

Hi Bix,

I had the same issue and fixed it by removing spaces from field names when creating your fillable PDF.

Hope that helps. Good Luck!

There are no spaces in the field names of the fillable PDF that I am using, so unfortunately this does not solve the problem for me.

Thanks, @Fawaz Naouchi, for the reply.


I included the same advice in the description and in the example app to alert everyone.

Hi Pedro,

No, it doesn't solve the issue. I already replied to Fawaz.

Hi Bix 

Can you share the stack trace from the error logs screen in service center app?

The issue could still be in the PDF Form itself. I just resolved an issue like this with a PDF Form I was working with. 

What I had to do was use Adobe Acrobat's "Prepare Form" feature that allows me to look at all the field names (not just the text next to the fields) and see where the issue is. For me what was causing the issue was not the spaces but "special" characters in the field names like this one:


Once I replaced that, I was able to save it and have it processed again and this time it worked.

Hope this helps!!
