sendDataToGlobalCable issue No matching member function

[ustk]

Trying to send back to the second cable, I get a No matching member function...
But I succeed receiving from the first cable

enum class GlobalCables
{
    dataCable = 0,
    sendBackCable
};

// Subclass your node from this
using cable_manager_t = routing::global_cable_cpp_manager<SN_GLOBAL_CABLE(-389806413),
                                                          SN_GLOBAL_CABLE(1515911406)>;


template <int NV> struct cubic_bezier_shaper: public data::base, public cable_manager_t
{
	//...

	template <typename T> void process(T& data)
	{
		//...
        
        this->sendDataToGlobalCable<GlobalCables::sendBackCable>(shaper); // No matching member function for call to 'sendDataToGlobalCable'
	}


private:
    
    span<float, 1024> shaper = { 0.0f };
}
