Validate Network Topology in a Web Application

Question

Hello everyone,

I am trying to develop a web application with Utility Network with ArcGIS Javascript SDK (4.27). I have prepared a Web Application with Utility Network widget and now I am trying to add the validate network topology widget. I have added the widget in this application but it does not allow me to validate the network topology.

The error/warning is that "A utility Network wasn't provided. the widget must be initialized with a utiltity network". However, I have already checked and it does have utility NEtwork. I am also able to perform tracing in UN Tracing widget.

In this application, I have used Web Map with UN feature service in it. The feature layer is shared from ArcGIS PRO (via Publish Web Layer).

QUESTIONS:

* If the warning is ""noDirtyAreasLayer": "Couldn't find the dirty areas layer. Add the dirty areas layer to the map.".* How can I add dirty Area layer in the Web Map? Should I add Feature Service or the Map Service?

* What are the use cases of Feature Service and Map Service? I am not sure for which case should I use feature service and for what is map service useful.

It would be of great help. Thanks a lot in advance.

Best Regards

Hello Shlesha,

I was wondering, do you get the same error message while working with Maps SDK for JavaScript 4.28,  4.29?

Also, do you know what version of ArcGIS Enterprise was your Utility Network published to?

Finally, can you create a pen I could use to plug my own data in to see if I can reproduce this behavior on my end?

Kind Regards,
Leo

Hello Shlesha,

Can you provide me with a copy of your code or at least a code snippet showing how your UtilityNetworkValidateTopology widget is being initialized so I can take a look at it?
