https://community.esri.com/t5/arcgis-online-questions/web-service-map-viewer-error/m-p/1648883#M66264 <P>&nbsp;</P><P>Good morning,</P><P>I started recieving this error on one of my maps. I have hosted feature layers that I created from shapefiles and a layer that was added via URL (web service). I can't remember how long ago it was, but I used to be able to modify and save this map with no issues. Recently, any time I try to make an update on the web map (symbology, label, etc.) I am not able to save. I attempted to remove the web service layer and I still get this same error. Any idea what's causing this (see error below)?

I removed it and now the map can save my modifications.&nbsp;</P> Tue, 09 Sep 2025 13:14:03 GMT https://community.esri.com/t5/arcgis-online-questions/web-service-map-viewer-error/m-p/1648908#M66267 fjramos 2025-09-09T13:14:03Z
