Maps will crash (RxJS error) on identify with some WMTS layers

[ale-cristofori]

Description

Related support issue is #2292
This bug seems to happen exclusively with client data and an example geostory map with client data can be found here

When having a WMTS layer loaded in the TOC

1. performing a click identify on the WMTS overlay layer will crash the map
   

2. clicking on an area where an overlay layer is not there will trigger a ReduxRJs error, blocking all subsequent interactions between user and map, see below
   

How to reproduce

• Open the geostory map linked above
• Click to identify on the overlay WMTS layer (osm_roads)
• The application will crash
• Re-load the map at point 1 (React error in console)
• Click to identify on an area where there is no overlay data
• The pop-up identify result will appear with a spinner showing but no results will show (RxJS error in console)

Expected Result

• Open the geostory map linked above
• Click to identify on the overlay WMTS layer (osm_roads)
• A pop-up will appear with the identify results for the overlay layer
• Click to identify on an area where there is no overlay data
• A pop-up warning of no results will appear on the map

Current Result

1. performing a click identify on the WMTS overlay layer will crash the map.

2. clicking on an area where an overlay layer is not there will trigger a Redux RJs error, blocking all subsequent interactions between user and map.
