NestJs and Mongoose ClassSerializerInterceptor return empty response

Is there an existing issue for this?

Current behavior

I have a project in nestJs, with mongosee, and I want to exclude certain properties from returned object. Specifically:

@Schema()
export class User {
  @Prop({type: String, required: true, unique: true, index:true})
  email: string;

  @Prop({type: String, required: true})
  username: string;

  @Prop({type: String, required: true, unique: true, index:true})
  handle: string;

  @Prop({type: String, required: true})
  @Exclude({ toPlainOnly: true })
  password: string;

  @Prop({type: String, default: () => randomBytes(16).toString('hex')})
  @Exclude({ toPlainOnly: true })
  emailVerifCode: string;

  //other properties
}

And when I try this:

@Post('login')
  @UseGuards(AuthGuardLocal)
  @UseInterceptors(ClassSerializerInterceptor)
  async login(@CurrentUser() user: User) {

    return {
      user: user,
      token: await this.authService.getTokenForUser(user)
    }
  }

I get returned an empty object. I also tried adding:

  app.useGlobalInterceptors(
    new ClassSerializerInterceptor(app.get(Reflector))
  );

All controllers I tried with ClassSerializerInterceptor returns an empty object.

To the main.ts but I get again an empty object as a response. I tried other solutions but none worked. Getting kind of desperate at this point.

Using: "mongoose": "^7.5.2", "@nestjs/core": "^10.0.0"

Minimum reproduction code

Steps to reproduce

No response

Expected behavior

Retrieve the user without the @Exclude fields

Edit: Updated the git repository to an open one. Deleted all unused modules and env variables, left db variable to allow testing (I'm using atlas and that DB is currently running). DB and secret will be changed after issue is resolved. To create a user in postman:

localhost:3000/user/register
{
    "email" : "email@email.com",
    "username" : "testuser",
    "handle" : "test",
    "password" : "Test12345.",
    "retypedPassword" : "Test12345."
}

To test the empty return:


{
    "username": "test",
    "password" : "Test12345."
}```
