Splice method not working in Flow Designer

[Community Alums]

Below code is written in Updating Responsibilities field of type List in Flow Designer:

var delvalue=fd_data.trigger.current.u_responsibility;// Single sys_id

gs.info('Value to be deleted:'+delvalue);

var existvalue=fd_data._6__for_each.item.u_authority_role;//Comma Seprated sys_ids

gs.info('Existin Values:'+existvalue);

//var arr=[];

var arr=existvalue.indexOf(delvalue);

gs.info('removed Index:'+arr);

existvalue.splice(arr,1);

gs.info('Left Values:'+existvalue);

return existvalue.toString();

the above is giving error in flow designer as below:

Error: Cannot find function splice in object false.,Detail: Cannot find function splice in object false.

You really should write better variable names. It's hard to understand your code due to those irritating names.

My proposal:

var arrValues = fd_data._6__for_each.item.u_authority_role.split(','); 
var numPosition = arrValues.indexOf(String(fd_data.trigger.current.u_responsibility || ''));

if (numPosition != -1) {
  arrValues.splice(numPosition , 1);
}

return arrValues.join(',');

@Maik Skoddow Sure will consider that will follow proper names
