NestJS fastify swagger errors while building app - node.js

Question

I'm using fastify adapter
According to the documentation I have installed the swagger adapter for fastify
npm install --save #nestjs/swagger fastify-swagger
And when I import swagger objects
import { DocumentBuilder, SwaggerModule } from '#nestjs/swagger';
Get multiple errors in the building app stage:

Has someone ideas what to do?

Answer 1

Okay, I have found the answer.
Open file tsconfig.json and add this line:
{
compilerOptions: {
"skipLibCheck": true
}
}
I'm not sure, that it is the best way because it will skip your node_modules checking while compiling. But to launch, it helps.
