Mapped-types from @nestjs/graphql is not generating metadata using PluginMetadataGenerator

[hari1602]

Is there an existing issue for this?

• [X] I have searched the existing issues

Current behavior

The extended types using PartialType from @nestjs/graphql is not generating the metadata. Since I'm using the swc-loader & monorepo structure, I'm following this step https://docs.nestjs.com/recipes/swc#monorepo. Is there anything I'm missing?

Minimum reproduction code

https://stackblitz.com/edit/nestjs-typescript-starter-pbexxs

Steps to reproduce

1. npm i
2. npx ts-node apps/repo/src/generate-metadata.ts
3. The generated file can be found at this path apps/repo/src/metadata.ts
4. The extended types for RepoUpdateInput from the metadata.ts file are missing

Expected behavior

1. The generated file (apps/repo/src/metadata.ts) should have the extended types using PartialType.
2. One example is RepoUpdateInput is extending the type from RepoCreateInput partially.
3. Expecting the RepoUpdateInput from the metadata.ts file should have the extended types.

Expecting the RepoUpdateInput from the metadata.ts file should have the extended types.

RepoUpdateInput class has only 1 attribute - id, which should be reflected in the metadata.ts file.

This output:

Is perfectly fine.
