Could not reproduce.

File not found error

On real device randomly occurs error: File Not Found Error - while trying to read from Storage

Error is already quite old. From CIQ_LOG.YML I see that it occurs roughly once a day. It is not as visible as before because Watch restart automatically Watchface.

    I'm seeing some ERA bug reports for File Not Found Error:

    Error Name: File Not Found Error
    Occurrences: 1
    First Occurrence: 2020-01-20
    Last Occurrence: 2020-01-20
    Devices:
        Forerunner® 945: 3.30
    App Versions: 0.0.8
    Languages: eng
    Backtrace:

        myView.onStop:1166

    Error Name: File Not Found Error
    Occurrences: 5

    Last Occurrence: 2020-01-20
    Devices:

        myView.handleSettingsChanged:1415
        myView.onUpdate:1505
        myApp.onUpdate:120

    It looks like it could just be for one user so far.

    saveMemoryData is just this:

    	function saveMemoryData()
	{
		var memData = [
			profileTimeData,
			positionGot,
			positionLatitude,
			positionLongitude,
			positionAltitude,
			profileActive,
			profileDelayEnd,
			profileRandom,
			profileRandomEnd,
			demoProfilesOn,
			demoProfilesCurrentProfile,
			demoProfilesCurrentEnd,
			-1,
		];
		applicationStorage.setValue(0, memData);
    }

    Hi Coleman,

    i just get this error on my WF. (No crash, at least didn't see any crash.)

    I just saw the battery has fallen from 78% to 18% in less than 2hours, so i took a look at logs and find this :

    ---
    Error: File Not Found Error
    Details: 'Failed invoking <symbol>'
    Time: 2019-12-22T13:36:24Z
    Part-Number: 006-B2859-00
    Firmware-Version: '8.00'
    Language-Code: fre
    ConnectIQ-Version: 3.1.6
    Store-Id: cf4501b9-5acb-4ed7-aef3-6573e7474871
    Store-Version: 73
    Filename: 9CB80551
    Appname: CubeWatch
    Stack:
      - pc: 0x1000232b
      - pc: 0x10006ca6

    (I'm not sure there is a direct link between battery and file error. the battery went to 10%, i put my watch off/on, and the level get back to 11% after 10/15mn ...and stop falling).

    I checked in xmlDebug and this is just when i try to get data back from disk, with Storage.getValue (=0x1000232b) . i can test to avoid this error, easily i think, instead of directly getValue...

    but it seems some event is called,  in which some Storage loading is set, and in the same time some Storage saving id done.

    I think one way to reproduce it would be to code a function loading storage data in some loop, and putting either clearValues() or setValue in Events (onHide, Sleep, settingsChanged.....)

    Hey Folks. We can't reliably reproduce this right now. If someone can reliably reproduce this and get us a project that will show it, then we might be able to get somewhere with it. Until then I'm going to close this, but I can reopen it if we get something more reliable.

    Hi guys. Is anything new about this issue? I have the same problem, unfortunately it  happens each couple of hours. It works perfectly on my device, only one user reported the problem yet. In my case it is not definitely related to null value, it is really only problem of getting value from storage. Is there at least some workaround how to prevent app from crash? I tried "try and catch", but it seems doesn't works. Many thanks in advance.
