UI Flows for desktop no longer working

[BenDenBlanken]

Hi all,

A generic topic title but all my UI Flows which I have previously build are no longer working. Last week I had build the calculator sample and another which worked fine. Now when I try to run them I get an error on the first step after the launch. The complete error is on the post below. All other desktop UI Flows I build have the same error.

Is this a known issue? It's kinda sad as I wanted to show this functionality at our local user group this tuesday 😅

Here is a screenshot of the flow:

Here is the complete error:

Hello, 

i've also faced the same issue...it seems to be a bug, however i managed to workaround the issue by editing the json related to the action and changing the character ";" to "," for the boundingRectangle property. 

Example: "boundingRectangle": "96,0,946,728"

Hope it helps

Hi,

Thank you this "worked". It's strange this now happens and very annoying to change all steps.

This is a bug on some international locale. We had released a QFE on 2/12. Please download the new one and try again it should fix the issue. Please let us know if you still see unexpected behaviors. Thank you very much for your feedback!
