Fill PDF Smart Service Add Image to Image Field

I am using the Fill PDF Smart Service from the PDF Tools plugin. I have a fillable PDF with an image field that I am trying to insert an image into. The image is stored in the knowledge center. I have the PDF Field value in the data tab set as such. 

{
    {"name": "image", "value": todocument(pv!documentId)
    }
}

However, it is not filling the field and there are no errors when running the process for debugging. Please advise.

  •  Apologies, for more context, we are wanting the ability to have non-technical team members set up their form templates in Adobe to be filled. We are then running these templates in an Appian process model to fill the forms with relevant data. Each form will need to have a dynamic image populated into an image field on the PDF itself. We have over 100 different PDFs we are looking to do this with, converting them to HTML is not an option.
