Coalease field script is not working to remove undefined values

[Vamshi_ch123]

Hi All,

I have unique identifier field marked as coalease and now filtering some undefined values from this using below script  is giving me the error message like this "Unable to resolve target record, coalesce values not present: [Script]"

(function transformEntry(source) {

    if (!source.u_serial_number || source.u_serial_number.toString() === "Undefined") {

        ignore = true;

    } else {

        return source.u_serial_number;

    }

})(source);

How to fix this

thank you

Hi @Vamshi_ch123 , 

Did you try with == instead of === operator. 

Add gs.log() in If condition and check which part is executing at run time.

-Thanks,

Hi Ashish,

Yes tried as below as well but still getting the same error 

(function transformEntry(source) {

    if (!source.u_serial_number || source.u_serial_number.toString() == "Undefined") {

        ignore = true;

    } else {

        return source.u_serial_number;

    }

})(source);

and without script it is working when i check with single record
