When consuming a web map with few feature services there, i keep getting this error in all our web apps which includes a range of both the ArcGIS JS 3.x API and the 4x API.
Can you have a look and fix this? It should be a quick fix.
https://static.arcgis.com/fonts/tahoma-regular/0-255.pbf This URL does not seem to be available ... and the JS API keeps logging this error. So you either make it available or handle it better in the JS API.
