Im forced to migrate from ArcMap to ArcGIS Pro. One of the features I use the most is Linear Referencing and showing points along routes. In ArcMap you can create your routes, and use the find function to locate individual points along these routes. Then you just right click on event table there is an option to display route events as a graphic. In ArcGIS Pro I have used the make route event layer tool from a csv table, then tried the locate features tool. I get the 000666 error (no OID).
