I troubleshooted this again and realized that the issue is that not all values of the routingPreference parameter are compatible with the trafficModel parameter. When the routingPreference is set to "TRAFFIC_AWARE" and the trafficModel parameter is used, the request fails. If the routingPreference is changed to "TRAFFIC_AWARE_OPTIMAL" instead, the request succeeds.
routingPreference = "TRAFFIC_AWARE", trafficModel parameter not used --> success
routingPreference = "TRAFFIC_AWARE", trafficModel parameter used --> failure
routingPreference = "TRAFFIC_AWARE_OPTIMAL", trafficModel parameter not used --> success
routingPreference = "TRAFFIC_AWARE_OPTIMAL", trafficModel parameter used --> success
Would you be able to update the documentation for the trafficModel (
