Hi Sheetal,
This is a field from nm:delivery table-
![prasannakumarmarru_0-1602566091755.png prasannakumarmarru_0-1602566091755.png](https://experienceleaguecommunities.adobe.com/t5/image/serverpage/image-id/27492i89AE358DBAA969D6/image-size/medium/is-moderation-mode/true?v=v2&px=400)
If application is not able to parse it, I think it is either referenced wrong in delivery input form or nms:delivery schema is changed and this field does not exist any longer.
I think it must have referenced as wrong in input form, there are many references to this field in that form. It has to be referenced as [/delivery/@contentEditingMode] in all the places.
