We are trying to merge an address fragment into an xdp by using the assembler service but we keep getting an exception as "com.adobe.internal.pdfm.xfa.XFAServiceException: PDFM_S28003: XFA Assembly unable to assemble required XFA Fragment".

I am trying to merge the two XDPs where one is an address fragment and another one is a form. I am using assembler service for the same and am gettting an error as "com.adobe.internal.pdfm.xfa.XFAServiceException: PDFM_S28003: XFA Assembly unable to assemble required XFA Fragment" even after passing the correct fragment name. Can you please help me to figure out this issue?

Check out this link, it describes how 2 XDPs are merged. Assembling Multiple XDP Fragments | Adobe Experience Manager
You need to have an insertion point in your form where to add the fragment(s) via Assembler
