Are you sure 'receivedValues' are not undefined? - where does it come from? — Oskar Szura

Your receivedValues variable seems undefined here, you should add more code to question.

receivedValues = req.body

do you use body-parser? you should use it to get properties from req.body

if(receivedValues && receivedValues[columnName] == undefined && (columnName=='name' || columnName=='price' || columnName=='duration' || columnName=='gender'))

you need to check if receivedValues exist

and you can optimize your code:

if(receivedValues && !columnName in receivedValues && columnName in usercolumns)
