Bug Report

Summary

Write a short summary of the bug in here.

• SDK Version: 4.5.2
• Expected behavior: @TypedException<BadRequestException>({ status: 400, description: 'Invalid parameter provided.' }) could find the exception type and generate Error case in Swagger document.
• Actual behavior: This @TypedException triggers NestiaSwaggerComposer.compose() erroring "Unable to find exception type".

Write detailed description in here.

Code occuring the bug

Referring to the case writing style from https://github.com/samchon/nestia/pull/548 , below is a shorter case that returns datetime where 400 is designated for invalid parameter request.

class HttpException extends Error {}

@Controller('get-datetime')
@ApiTags('Datetime')
export class DatetimeController {
  /**
   * /api/get-datetime
   */
  constructor(
    private readonly datetimeService: DatetimeService,
  ) { }

  /**
   * Retrieves the current date and time.
   *
   * @summary Retrieve Current Datetime
   *
   * @param timezone The timezone identifier (e.g., "UTC", "America/New_York").
   * @returns The current date and time in the specified timezone, in ISO 8601 format.
   */
  @Get()
  @Header('Content-Type', 'text/plain')
  @TypedException<HttpException>({
    status: 400,
    description: 'Invalid parameter provided.',
  })
  public getDateTime(
    @Query('timezone') timezone?: string,
  ): string {
    return this.datetimeService.getCurrentDatetime(timezone);
  }
}

I would always get the following error log:

.../node_modules/@nestia/sdk/src/NestiaSwaggerComposer.ts:134
  throw new Error(`Error on NestiaSwaggerComposer.compose():\n${messages}`);
        ^
Error: Error on NestiaSwaggerComposer.compose():
dist/apps/.../main.js - DatetimeController.getDateTime() from exception (status: 400):
  - Unable to find exception type.

The same log would be triggered when I import NestJS's HttpExceptions:

@TypedException<BadRequestException>({
    status: 400,
    description: 'Invalid parameter provided.',
  })
