Problems Creating SelectCommand from lambda function and std::vector<std::pair<std::string, std::unique_ptr<frc2::Command>>>

[webbbt456]

I am trying to create a SelectCommand at runtime. The commands are created by reading a json file during RobotInit.

Code:

#include <frc2/command/Commands.h>
#include <frc2/command/SelectCommand.h>

frc2::CommandPtr createSelectCommand(std::function<std::string()> selector
           , std::vector<std::pair<std::string, std::unique_ptr<frc2::Command>>> &&commands) {
  return frc2::SelectCommand(selector, commands).ToPtr();
}

/*
// commandSelector returns  a std::string
[this, commandSelector]() -> std::string { return commandSelector();}

*/

Line 76 of the file SelectCommand.h specifies a templated constructor that seems to match my parameters, but I have not found a way to have the compiler correctly compile the code.

I get the following errors:

cannot deduce class template arguments

no instance of constructor "SelectCommand" matches the argument list argument types are: (std::function<std::string ()>, std::vector<std::pair<std::string, std::unique_ptr<frc2::Command, std::default_delete<frc2::Command>>>, std::allocator<std::pair<std::string, std::unique_ptr<frc2::Command, std::default_delete<frc2::Command>>>>>)
