In ArcGIS online Web App Builder in the Configure Basemap Gallery I get a spatial reference error when adding a pass through service for a basemap "The basemap you are adding has a different spatial reference from the current map" Previous maps/web apps built using web app builder display the services but I cannot create new base map services to new web apps. The projections are the same. Has anyone found a workaround or is this a bug with the recent update to ArcGIS Online.
Solved! Go to Solution.
From what I understand, it is not enough that the projection/datum is the same if wanting to change basemaps. The tiling schemes must also be the same. ESRI's tiling schemes usually are 256x256. I have not had success with changing to a basemap (with vector tiles) with tiling scheme of 512x512 without making the Web AppBuilder app from scratch. This is possible in Web Map but not in Web AppBuilder in a easy way. I hope ESRI will give us this option also in WAB (and not forget that not all can migrate to Experience Builder before we have the relevant widgets we need there)!!
