get a PolyLine path to go to center of screen

Question

I am trying to draw a polyLine to the center of the screen (as the second path, point B) ... I tried referencing the below to get center: any pointers? coordinatesBx = map.extent.getCenter().getLatitude(); coordinatesBy = map.extent.getCenter().getLongitude(); The above errors with cannot getCenter() of undefined... should I try to get this in screenPoints first, then try to convert to lat long? I am good with my first two start points as lat long coords, i.e. workingStartA and workingStartB; however I cannot get the second coordinatesBx and coordinatesBy to go to center of screen. I am in arcgis-JS 4.11 specifically. i.e. var polyline = { type: "polyline", paths: [ [workingStartA, workingStartB], [coordinatesBx, coordinatesBy] ] }; arcgis-javascript-api arcgis-javascript-api-4

You are mixing up 3.x and 4.x syntax. Remember that in 4.x, a map doesn't have an extent (see Maps and Views in the documentation). Instead, you want to get the extent of the MapView. And the extent doesn't have a getCenter method. It has a center property, resulting in a Point that has a latitude and longitude property.
