Thank you for reporting this to us. I have passed this information to the team for further investigation. As a workaround, are you able to change the value to a string in your application?

3

I have no control of the Json string as it will be passed by calling application.

By the way, is there a method in PDFTron to take XML (with namespace and prefix) as input string instead of json?

4

Hello, at this time, the only input strings we support is JSON. Are you able to pre-process the JSON on your side to modify it?

5

I cannot modify the json as it is unknown to the application. The caller is passing the json string and the template and the application will call to PDFTron to generate the PDF.

Thank you for the clarification. As mentoned previously, the team is looking into this and I will provide you with an update as soon as I have it.
