upgrading to 4.0.0

I following the docs I can’t see why I am getting this error. Tried to follow the docs but it does not apply to my case. The docs have:

How to reflect

In general, there are only a few steps to be done:

    In package.json: set "type" field value to "module" -- My packge.json does not have this.


    In tsconfig.json: set "module" to ESNext or ES2020 - module is set to CommonJS if I try one of these I get -> SyntaxError: Cannot use import statement outside a module for every import in the project 


    In tsconfig.json: set "target" to ES2015 or newer - target is set to ES2021

• My code

import {bootstrap} from 'fastify-decorators'

• Logs

Error [ERR_REQUIRE_ESM]: require() of ES Module /home/user/Documents/offtopic/api/node_modules/fastify-decorators/index.js from /home/user/Documents/offtopic/api/src/lib/app.ts not supported.
Instead change the require of index.js in /home/user/Documents/offtopic/api/src/lib/app.ts to a dynamic import() which is available in all CommonJS modules.

@unematiii,

Just released v3.12.0 with Fastify v4 support.

There’s currently 2 limitations which prevents type providers from work:

1. FastifyInstance type is lost in controllers/services, hence they don’t know about selected type provider
2. Typescript currently can’t infer any type information from decorators - https://github.com/microsoft/TypeScript/issues/48885#issuecomment-1113861727
