Portal for ArcGIS 11.3: Instant apps minimalist broken

[NicolasGIS]

Hello,

After upgrading from 11.1 to 11.3, I noticed that my "Instant apps minimalist" are no longer fonctionnal.

I know it's deprecated:

https://doc.arcgis.com/en/instant-apps/11.3/create-apps/minimalist.htm

But still, supposed to work:

And I did not find any mention of it on "Retirements notices":

https://enterprise.arcgis.com/en/get-started/latest/windows/what-s-new-in-arcgis-enterprise.htm#ESRI...

I believe it's because it's using Maps SDK for Javascript 4.29 and watchUtils is no longer there:

Did I miss anything ?

Thanks,

Best regards,

Nicolas

@NicolasGIS yep I can also confirm there's no minimalist app in our 11.3 enviornment. I would hazard a guess that the app wont work in 11.3 now, and that the deprecation notice is incorrect.
Have you opened the app with dev tools open and viewed the console logs?

[NicolasGIS]

Yes, did you not see the console screenshot ? It's broken because watchUtils is gone.

apologies, missed the screenshot. if you have the time, please raise a ticket with myesri and hopefully they can rectify/clarify one way or the other

Hello Nicolas,

WatchUtils was deprecated at version 4.24.  Deprecated classes are removed after three release cycles.  The last version to have watchUtils was version 4.27 and they were removed at 4.28.

https://developers.arcgis.com/javascript/latest/4.28/#removal-of-watchutils

ArcGIS Enterprise 11.2 was using 4.27.  ArcGIS Enterprise11.3 is the first version to not have them. 

WatchUtils was replaced by reactiveUtils.  If the you have some custom functionality working with the watchUtils, you should rewrite that code to use reactiveUtils.

Hope this helps, let me know if you have any follow up questions!
