[Qlik Sense 2017 patch 1] Question about exception in my extension for copy selections between applications

[Anonymous]

Hello, Experts!

I had written (may be 1, or 2 years ago) an extension, that copy selections from one application and set copied selections to other.

My src:

CopySelections-qlik-extension/CopySelections.js at master · marley-js/CopySelections-qlik-extension ...

I used QS 3.0

-----------

I did not work with QS some period.

But now managers updated their QS to latest.

After update we receive next error. (May be the problem was earlie, i did not use desktop version)

Qlik_Sense_Desktop

In logs we can see only next messages about errors:

***
