getStressHistory crashing

Hi, good day to all.

I'm running the code below to get today's stress data:

var clockTime = Time.Gregorian.info(Time.now(), Time.FORMAT_MEDIUM);

var midnight = new Time.Duration(clockTime.hour*3600 + clockTime.min*60 + clockTime.sec);

var stressIterator = SensorHistory.getStressHistory({ :period => midnight, :order => Sen.ORDER_OLDEST_FIRST});

It works fine and give me what I want almost always, however, when it's shortly after midnight (00:00, 00:01, etc) it crashes. The crash is at the third line of the above snippet, it says only:

Error: Invalid Value
Details: Failed invoking <symbol>

Notice that I'm simply requesting stress history and saving the return to a variable. At this point I'm not trying to access a property of "can be null" entity. This happens both in the simulator and physical device (Venu 2). To reproduce this error, I set the computer clock to 00:00:00 and run it.

Thanks in advance.

That error means you have a local variable that's not used. You define it and set it but never use it
```
var a=3;
if(some condition) {
    a=5;
}
System.println("a="+a);
```
In the above, you'll get the warning if you comment out line 5

in the code you posted, you'll get it on line 171 and 173 as you set variables but then never use them. It's a warning you can probably ignore when you are testing/debugging

Hi Jim, thanks for the reply. Yeah, I check for nulls belowin the code. But even if I don't use the sensor iterator, it crashes. The code below is certain to crash (notice the function ends)

The crash may be a line or two off. Add some null checks. For example, what happens if stressIterator is null? (that could happen)
