Screen Widget not responding in ArcGIS Web AppBuilder - ArcGIS Enterprise 11.4

AbiDhakal

Hello GIS friends,
Good morning, and happy Friday!

I’m currently running ArcGIS Enterprise 11.4 and am experiencing an issue with the Screening widget in my Web AppBuilder. Specifically, I’m unable to configure the widget—it remains unresponsive. After I click to add the widget and navigate to the Analysis tab, when I attempt to add layers, nothing happens.

I’ve been using this widget in my Web AppBuilder for years without any issues, but this morning when I tried to work on it, the widget stalled. I thought it might need to be reconfigured, but when I attempted to do so, it remained unresponsive. Interestingly, the widget works fine in ArcGIS Online, but not in my Enterprise environment.

Any assistance or suggestions would be greatly appreciated.

Thank you so much,
Abi

I was able to isolate the issue that was causing problems in ArcGIS Enterprise 11.5 with my Web AppBuilder (WAB) application and the Screening widget.

After some testing, I found that the following NOAA REST service was triggering the issue:

https://gis.charttools.noaa.gov/arcgis/rest/services/MCS/NOAAChartDisplay/MapServer/exts/MaritimeChartService/MapServer

Once I removed this layer from the web map, the Screening Widget immediately started working again.

I'm not sure exactly what about this NOAA service is causing the problem, but a few possibilities come to mind:

• It is standard map service vs. feature layers
• The service may be running on an older ArcGIS Enterprise version (10.9.x).
• The layer structure contains grouped or nested layers that the widget may not handle correctly.

I also noticed that I couldn't add the service back into the application using the Add Data widget. As soon as the layer is added to the web app, the Screening widget locks up and becomes unusable.

I wanted to share this finding in case others are experiencing similar issues with Enterprise 11.5, Web AppBuilder, or the Screening widget.

If you're troubleshooting the Screening widget that suddenly stops working, it may be worth reviewing any specialized map services included in your webmap table of contents (layer list). Hope this help the next person out.
