I see this error in every delivery and i looked for entire nms:delivery data schema and dont find keyword contentEditingMode.
any guidance ?
This is a field from nm:delivery table-
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.
