AWS Location Service boto3 Error: ResourceNotFoundException

Question

I tried to create a route with AWS LocationService. But when I run my code I get an error and I don't understand what it means…

Can you help me to understand what I did wrong?
Am I missing some credentials?

But even if I use the SearchPlaceIndexForPosition I get some information about the position. So I don't think it's a credential issue...

import boto3
location=boto3.client("location",region_name="eu-central-1")
response = location.calculate_route(CalculatorName='Default',
                                    DeparturePosition=[10.00759,53.54930], # Hamburg
                                    DestinationPosition=[6.95703,50.94176] # Cologne
                                    )
