Update the description field with catalog variable description on sc_task form

[Sri29]

I have below after business rule to run on Insert, which supposed to insert description on the sc_task by reading all the catalog variables descriptions record but it doesn't. If I change the case to before business rule, it gives error when inserting the record as 'Invalid insert' on page and also a flow associated to this fails as I see it doesn't like  grTask.update() call at the end. Any advise on what would be the best way  to resolve the issue.?

(function executeRule(current, previous /*null when async*/ ) {

    var grTask = new GlideRecord('sc_task');
    grTask.get(current.getUniqueValue());
    var summaryStr = '';
	
    for (var key in grTask.variables) {
        //if key is empty discard the entry
        if (grTask.variables[key].getLabel()) {
            summaryStr += grTask.variables[key].getLabel() + " ==> " + grTask.variables[key].getDisplayValue() + "\n\n";
        }
    }
    grTask.setValue('description', summaryStr);
    grTask.update();
}

@Sri29 Change the business rule to before insert and add the following script in the script field.

(function executeRule(current, previous /*null when async*/ ) {

    var summaryStr = '';	
    for (var key in current.variables) {
        //if key is empty discard the entry
        if (current.variables[key].getLabel()) {
            summaryStr += current.variables[key].getLabel() + " ==> " + current.variables[key].getDisplayValue() + "\n\n";
        }
    }
    current.setValue('description', summaryStr);
}

Since this business rule runs before insert no need to use current.insert() or current.update() in this case.

Hope this helps.
