ESRI JS API 4.27: scale based symbology not systematically honoured depending on instantiation

Question

Hello,

Using ArcGIS Enterprise 11.1, I published a scaled based symbology FeatureServer and MapServer:

https://pro.arcgis.com/en/pro-app/latest/help/mapping/layer-properties/scale-based-symbol-classes.htm

I created a JS API 4.27 application and noticed that my FeatureLayer does not honour this scaled based symbology. Digging a little more, I understood that it depends on its instantiation:

- Instantiation with portalItem, works:

is there a solution available to use scale based symbols with feature services (in Map Viewer of portal 11.3)?

So support added my case to the following already logged BUG and limitation:

BUG-000154352
The symbology scale range display is not retained for a feature service in a Portal for ArcGIS web map.

To me this BUG title is bit misleading as it does work for a feature service in the webmap if it is added as Portal item (look for content in the Portal and then add the feature service item). It is only not supported if you had the service by URL (either FeatureServer or MapServer/id) as it does not retrieve the symbology described in the Portal item but instead directly from the ArcGIS Server.

It would have been better to enlarge a bit the scope of this BUG to ArcGIS Server services (both FeatureServer service and featureLayer created from a MapServer layer) rather than restricting it to some webmap use.

Anyway, thanks for having chimed in @KristianEkenes! Feel free to ping anyone from Pro/Enterprise side 🙂

Thanks for the reply.

I opened a case. Let's see if the routing works.

Personnaly, I found it a pity: I tend to prefer referencing service by URL which are more stable to me (can be republished). Also, creating a FeatureLayer from a MapService layer is really convenient as well.

Thanks,
