Bump to fastify 3.27.4, causes error "All declarations of 'FastifyInstance' must have identical type parameters.ts(2428)"

[flipperlite]

Thanks for the tutorial. Your repo opens without any errors. I was trying to get your code to work in the latest version of Fastify 3.27.4. Unfortunately, I'm getting the following error after I bump the versions. I've already commented on an existing, closed issue. Should I raise a new issue? Do you have an updated tutorial or example with the latest version? Thanks.
