Importer Error(with rowEdit) - angular.min.js:108 requested row not found in rowEdit.setRowsDirty, row was: [object Object]

Implemented Importer functionality and everything works fine except when I get the following error on the console from adding new row to the grid on this line of code - allRows.unshift({

Error message: angular.min.js:108 requested row not found in rowEdit.setRowsDirty, row was: [object Object]
