I am trying to run the ortools_pubcrawl.ipynb example from GitHub - GIScience/openrouteservice-examples: (Mostly) real-world examples and inspirations to use the , but I’m stuck at the first cell that uses ortools. Here is the error returned by executing that cell,

TypeError: Wrong number or type of arguments for overloaded function 'new_RoutingModel'.
Possible C/C++ prototypes are:
operations_research::RoutingModel::RoutingModel(operations_research::RoutingIndexManager const &)
operations_research::RoutingModel::RoutingModel(operations_research::RoutingIndexManager const &,operations_research::RoutingModelParameters const &)
Can anyone provide guidance as to how to get this working? Thanks!
