Description

Trying to migrate JS->TS for a NodeJS backend service. After changing index.js -> index.ts all my fastify plugins are fine (e.g. FastifyOpenapiDocs, FastifyMultipart, FastifySentry), but FastifyAuth has this error:

No overload matches this call.
  Overload 1 of 3, '(plugin: FastifyPluginCallback<{ defaultRelation: string; }, RawServerDefault, FastifyTypeProvider, FastifyBaseLogger>, opts?: FastifyRegisterOptions<...>): FastifyInstance<...> & PromiseLike<...>', gave the following error.
    Argument of type 'typeof fastifyAuth' is not assignable to parameter of type 'FastifyPluginCallback<{ defaultRelation: string; }, RawServerDefault, FastifyTypeProvider, FastifyBaseLogger>'.
      Type 'typeof fastifyAuth' provides no match for the signature '(instance: FastifyInstance<RawServerDefault, FastifyTypeProvider, FastifyBaseLogger>'.

  Overload 2 of 3, '(plugin: FastifyPluginAsync<{ defaultRelation: string; }, RawServerDefault, FastifyTypeProvider, FastifyBaseLogger>, opts?: FastifyRegisterOptions<...>): FastifyInstance<...> & PromiseLike<...>', gave the following error.

Steps to Reproduce

Code looks something like:

// index.ts
import * as FastifyAuth from '@fastify/auth';

fastify.decorate('authfunc1', authfunc1);
fastify.decorate('authfunc2', authfunc2);
await fastify.register(FastifyAuth, { defaultRelation: 'and' }); //error under `FastifyAuth`

Expected Behavior

No response

import { fastify as Fastify } from "fastify"
import { fastifyAuth } from '@fastify/auth';

const fastify = Fastify({})
await fastify.register(fastifyAuth, { defaultRelation: 'and' }); //error under `FastifyA
