Does ignoreInvalidLocations work for Non-traversable network element?

Hi All,

When solving the route problem with ArcGIS Map SDKs for JavaScript 4.27, I got an unexplained result. There are 3 stops on the map and the 2nd stop should be a non-traversable network element position. However, the api returns the response with a route which curb approach is incorrect for 2nd stop.

attention: the curb approach for 2nd stop is 2 (left-side).

This is the result shows in ArcMap 10.8.1

Is there any missing parameters in solving the problem?

Addition Information:
The response from https://route-api.arcgis.com/arcgis/rest/services/World/Route/NAServer/Route_World/solve shows the curb approach is 2 (Left side)

Does it make sense?

Thanks,
Leo
