Generated xxxCdrAux.hpp has data type casting issue for large recursive data structure

[rookybird]

Hi all, I am using fastddsgen v3.1.0. When I compiled the generated xxxCdrAux.hpp, there was an narrowing conversion error "error: narrowing conversion of ‘12144122424’ from ‘long unsigned int’ to ‘uint32_t’ {aka ‘unsigned int’} [-Wnarrowing]".

I used recursive sequence in the idl.

typedef sequence<WaypointNode, 100> SingleLane;
typedef sequence<SingleLane, 100> SingleChannel;
sequence<SingleChannel, 100> route

The structure has to be this big. Any thoughts to fix the error?

I will attach the idl files below.
