Processing of reports about JavaScript exception

Question

We receive reports about exceptions for our app in Windows Store. The app is written on JavaScript. We have questions about content of some cab files.

First one:

StackTrace=ms-appx://nanosecurity.nanoantivirusskyscan/default_VS2012.html:301:9           rethrowPromiseError()
           ms-appx://nanosecurity.nanoantivirusskyscan/default_VS2012.html:1:291           WinRT Promise.done()()
           ms-appx://nanosecurity.nanoantivirusskyscan/default_VS2012.html:1:49           Promise handler()
           ms-appx://nanosecurity.nanoantivirusskyscan/default_VS2012.html:1:223           WinRT Promise object for Windows.Foundation.IAsyncOperation`1<Windows.ApplicationModel.Background.BackgroundAccessStatus>()

The methods are not methods JS. The file ms-appx://nanosecurity.nanoantivirusskyscan/default_VS2012.html doesn't contain JS . So it seems strange for us.

Second file contains the following:

SourceFile=ms-appx://microsoft.winjs.1.0/js/base.js
Line=9731
Character=9

and

StackTrace=ms-appx://microsoft.winjs.1.0/js/base.js:9731:9           DOMWeakRefTableInit
           ms-appx://microsoft.winjs.1.0/js/base.js:9626:2           Global code
           ms-appx://nanosecurity.nanoantivirusskyscan/js/bgscript.js:3:2           Global code

So here: "ms-appx://nanosecurity.nanoantivirusskyscan/js/bgscript.js:3:2" import of script happens:

importScripts ("ms-appx://microsoft.winjs.1.0/js/base.js")

There inside of the file "ms-appx://microsoft.winjs.1.0/js/base.js" the error occurs in the line 9731. It looks like the error occurs on the side of Microsoft code.

We placed cab files here:

Could you check and assist us?

Thank you.

If my reply answers your question, please mark this post as answered.

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.

Answer 2

These files are actually located in your project under references\Windows Library For JavaScript 2.0\js.   I looked at the version of the files I have and they don't match yours.   Can you look at the ones that are part of your application and determine what is going on?

Hi Bret, if i understood you right, you doubted about the version of Microsoft library we used so I placed it here https://onedrive.live.com/redir?resid=340FE2FBFC915FFA!153&authkey=!AJDsgCzi7Fayy-I&ithint=file%2cappx

If I understood you wrong, could you please explain again what information do you need?

Thank you.

Hi guys,

Any news?

Answer 9

 I cannot repro your issue.  I suggest you debug your project by walking through the javascript code.  If not, then Please post a zip file with steps on how to see the problem.
