I have seen similar questions posted but not answered.
I am trying to solve a vehicle routing problem and the Network Analyst shows two errors:
Error: "Failure while working with internal route problem instance"
Error: "A column was specified that does not exist."
After clicking solve the algorithm runs well. I have outputs in route properties, but there is no route on the map. I can see only the sequence of orders.
I want the output to display "True Shape" routes, but the only geometry method that will not lead to errors is the "Straight Line".
Any input or help on these errors would be much appreciated.
