Compare future value in Due date(in Task A) with current Date time and if matches then create Task B

[Rekha10]

I need to create Task B in a custom table (In custom app) when either of the following conditions are met:

STC_flag = Yes and Next Activity = Y, OR STC_flag = Yes and the Due Date/Time of Task A equals the current date/time.

Due date holds a future value, Code 1 is to capture that value.

Code1:

var gdt = new GlideDateTime();
return addBusinessDays(gdt,3);

function addBusinessDays(gdt, daysToAdd) {
var count = 0;

while (count < daysToAdd) {
gdt.addDaysLocalTime(1); // move forward one day

// 1 = Monday … 7 = Sunday
var dayOfWeek = gdt.getDayOfWeekLocalTime();

if (dayOfWeek != 6 && dayOfWeek != 7) {
// Not Saturday or Sunday → count it
count++;
}
}

return gdt;

I have created an Action in flow designer to capture current date and time, mention in Code 2:

(function execute(inputs, outputs) {

    outputs.now = new GlideDateTime().getValue();

    return outputs;

})(inputs, outputs);

In flow designer I used action "wait for condition" to compare Due date and Variable in custom action, expectations are that when they match then Task B should create but it didn't work, below is FlowDesigner screenshots of action, flow and test flow execution. 

Please advise the solution, how to achieve this
