Unable to prefill a XFA based PDF with Adaptive Form data submission

Hi all,

I am trying to prefill an XFA form (XDP based) through data that is submitted through an Adaptive form.

My Adaptive form is based off a JSON (Schema.json) attached. I bound each of the adaptive form field to this JSON. On the other side, I bound my XDP to a XSD file (attached).

when i submit my Adaptive form, the form gives out the JSON (response.json), I am using a servlet to convert this to an XML (response.xml) and then use Render Service to stitch together a prefilled PDF form. But this is not working, i always get a blank form without any prefilled data.

But when i use same XML and try previewing through AEM Forms designer, the PDF gets prefilled. Not sure what i am missing. I am attaching all the files that i used here. Would be really helpful if someone from the community can assist.

response.json (data submitted as JSON from Adaptive form)

{"moneylink-trans-amount":1000,"financial-inst-name":"Sample Bank","acc_number":1.2312312E7,"checkbox-journal-amt":"1","total-journal-amt":1000,"from-acc-number":1.2312312E7,"from-acc-reg":"Sample Savings","employer-business-name":"Sample Corp","Emp-Fed-Tax-Num":"12312312","bus-street-addr":"123 Main St","City":"Sample City","zip":"12345","telephone":" 11232212321","IRA-Acc-Number":"123456789","checkbox_deposit":"1","checkbox-transfer":"0","employer-sign":"John Doe","applicant-print-name":"Jane Smith","current-date":"2025-08-19"}

response.xml (JSON converted to XML AEMFD by custom AEM Servlet)

XML used in Preview of AEM forms designer, which works and prefills. I am converting this XML to AEM FD XML document to send it to Render service
