SensorHistory issue?

hi everyone,

I get a weird SensorHistory issue:

Error: Unexpected Type Error
Details: Failed invoking <symbol>
Exception: UnexpectedTypeException: Expected null/Number, given null

here is my code:

function getIt(w,opt){
	var D=null,options = {:period=>opt};
	var AMI = [:getHeartRateHistory,:getOxygenSaturationHistory,:getBodyBatteryHistory,:getStressHistory];
	if(Toybox has :SensorHistory && SH has AMI[w]){
		var gM = new Lang.Method(SH, AMI[w]);  
		gM = gM.invoke(options);
		if(gM!=null){D=gM;}
	}
	return D;
}

where SH = Toybox.SensorHistory,

the crash happen here: gM = gM.invoke(options);

I also tried gM = gM.invoke({}); with same result.

it is included in a loop and it happens with getOxygenSaturation

The odd thing is that it does not happen on every devices (simulator)

So far I saw this with F6, Enduro and MARQs, but everything is fine with F7 EPIX etc.

Is it an issue known from the simulator or am i missing something?

have a great day.

I know there were a bunch of bug reports with getOxygenSaturationHistory and don't recall if they were all on devices or if there were some in the sim. Since it hasn't been working right on devices…

Which sensor history is it failing on? The devices it's failing on don't have the System5 APIs in the sim,

Ok, I see it was getOxygenSaturationHistory. That has never worked right on some devices.

I think only on simulator, I use the same functions on other stuff and never heard about this (and used to work on the SIM also)

I forgot to mention it but off course everything is up to date (SDK, devices, plugins)

that is why there is a has check.

yes, it's a bug for those devices for spo2 from history but if you want only last value use currentOxygenSaturation

thanks! It is what I do, even for HR, I use this to get min/max, you mean for those devices on real or only on sim?

_psx_ over 4 years ago in reply to Shent-Aurkhan (SHN)

on sim for sure so I've decided to not implement it for caution.

for this devices only solution is:

var si = SHI.getOxygenSaturationHistory(null);

and you can read min/max from si

hum even if I do this, it crashes...

impossible my code

if((Toybox has :SensorHistory) && (SensorHistory has :getOxygenSaturationHistory))
       {
           try
           {
               si = SHI.getOxygenSaturationHistory(null);
           }
           catch(ex)
           {
               si = null;
           }
       }

       if((si != null) && (si.getNewestSampleTime() != null))
       {
           //do something with si.getNewestSampleTime().value()
       }else
       {
           // no data
       }
