Errors on loading dynamic map layer and feature layer

SarojThapa1 — Sat, 11 Dec 2021 20:58:53 GMT

When the map is loaded, sometimes it displays dynamic map layer and legends and sometimes it does not. I am not sure this is the error caused by ArcGIS Server Manager because other maps are loaded fine from the same ArcGIS Server. Could anyone please check my codes below and tell me what possibly is wrong? Thanks

Re: Errors on loading dynamic map layer and feature layer

Saroj,

Why are you using "FeatureServer" in almost all your urls instead of "MapServer"? Do you understand the difference between the two?

I need to have popups and edit (both attributes and geometry) functions for a couple of feature layers. That's why I am using Feature Server. To load the entire map at once, I am using MapServer. I don't know if there are better options than what I am using right now. Thanks

Saroj,

OK if you need editing then yes you need to use FeatureServer but if you do not need to edit the layer then use MapServer. I don't see anything wrong with your code so you should check your ArcGIS Server logs to see if your services are failing.

Thank you so much Robert. You have been helping me a lot lately.
