Current behavior

We are upgrading our app from NestJS9 to NestJS10. While doing the upgrade we noticed the following. As in the Screenshot now the JSDocs comments are parsed as just literals and include @ type & @ memberof in the swagger doc this worked fine before v10 of NestJS creating swagger docs without messing up with other jsdocs attributes.

Upgraded @nestjs/swagger v 6.0.4 to 7.3.1

cli config

  "collection": "@nestjs/schematics",
  "sourceRoot": "src",

    "plugins": [
      {

          "introspectComments": true
        }
      }
    ]
  }
}

affected jsdoc

export class UserListFilterDto extends OffsetPaginationBaseDto {
  /**
   * Filter users by firstname lastname or email
   * @example 'q'
   * @type {string}
   * @memberof UserListFilterDto
   */
  @IsOptional()
  @IsString()
  query?: string;

  /**
   * Filter by user role
   *
   * @type {Roles}
   * @memberof UserListFilterDto
   */
  @IsOptional()
  @IsEnum(Roles)
  role?: Roles;

  /**
   * Sort users, defaulted to `desc` by `created at`
   *
   * @type {SortOrder}
   * @memberof UserListFilterDto
   */
  @IsOptional()
  @IsEnum(SortOrder)
  order?: SortOrder = SortOrder.DESC;

  /**
   * Sort users
   *
   * @type {UserListSortBy}
   * @memberof UserListFilterDto
   */
  @IsOptional()
  @IsEnum(UserListSortBy)
  sortBy?: UserListSortBy = UserListSortBy.CREATED_AT;
}

I just tested with nestjs v10 (@nestjs/swagger@7) and nestjs v9 (@nestjs/swagger@6)

So I don't think that this is a regression
