This is related to positioning of the signature field on the PDF Form while designing.

Error seen:

"error" : {
"code" : "ServerErrorException", "message" : {
"lang" : "en-US", "value" : "Cannot invoke \"org.apache.pdfbox.cos.COSArray.get(int)\" because \"fieldAreaArray\" is null"


Adjust the positioning of the signature field by placing it correctly and make sure all the position parameters (left, top, height, width), x/y coordinates etc are in float and not integer. 

Delete and create the fields again to resolve this issue, and while creating the field, ensure space is left from the margin and with other PDF content to avoid encountering this issue again.
