In a basic typescript project:
server.ts:

import * as Fastify from 'fastify'
import * as fastifyJwt from 'fastify-jwt'

const fastify = Fastify()

fastify.register(fastifyJwt, {
  secret: 'supersecret'
})

fastify.post('/signup', (req, reply) => {
  // some code
  const token = fastify.jwt.sign({ "foo":"bar" })
  reply.send({ token })
})

fastify.listen(3000, err => {
  if (err) throw err
})

tsconfig.json:

{
  "compilerOptions": {
    "module": "commonjs",
    "target": "es6",
    "noEmit": true,
    "strict": true,
    "noImplicitAny": true
  },
  "include": [
    "server.ts"
  ],
  "exclude": [
    "node_modules"
  ]
}

Running this basic build command results in the following error:
