Issue

Currently, servers using this library logs this kind of errors: [FSTDEP014] FastifyDeprecation: You are trying to set/access the default route. This property is deprecated. Please, use setNotFoundHandler if you want to custom a 404 handler or the wildcard (*) to match all routes..

This is because of this deprecation https://github.com/fastify/fastify/commit/fc81c707b819894bd84a903e5bbd23ec121e5a7b.

The issue to help tracking dependency adoption.
