Version of Boost
1.84.0

Code:

class X
{
public:
	X() : x(false) {}
	X(bool x) : x(x) {}
protected:
	bool x;
	BOOST_DESCRIBE_CLASS(X, (), (), (x), ())
};

int main()
{
	try
	{
		boost::json::value jv = { { "x", 0 } };
		auto a = boost::json::value_to<X>(jv);
	}
	catch (std::exception const& e)
	{
		std::cerr << "Error: " << e.what() << std::endl;
	}
}

This would faild and throw an exception: Error: value is not boolean

Yes. This is by design. 0 is not a boolean value.
