Ouch!

include/yaml-cpp/node/detail/node_iterator.h:56:19: error: 'template<class _Category, class _Tp, class _Distance, class _Pointer, class _Reference> struct std::iterator' is deprecated [-Werror=deprecated-declarations]
   56 |     : public std::iterator<std::forward_iterator_tag, node_iterator_value<V>,
      |                   ^~~~~~~~

Why aren't other PRs seeing that problem?

we need to upgrade the yaml-cpp to 0.7.0 anyway? ( assuming the current version is 0.6.x ) https://github.com/jbeder/yaml-cpp/commit/26faac387c237ccac75a56925c6858baf8ccda1b
