Current behavior

I think there is a problem with referring to the src dir. but The build foler is dist dir.

npm run start:dev => OK npm run start / npm run start:prod => Fail

I use nestJs hot-reload function It was normal before the openapi(swagger) cli plugin of nestjs was applied.

All config setting followed the official document of the nestjs

Expected behavior

Minimal reproduction of the problem with instructions

farm.controller.ts

import { Controller, Get, Post, Body, Patch, Param, Delete } from '@nestjs/common';
import { FarmService } from './farm.service';
import { CreateFarmDto } from './dto/create-farm.dto';
import { UpdateFarmDto } from './dto/update-farm.dto';
import { Farm } from './entities/farm.entity';

@Controller('api/v2/farms/test')
export class FarmController {
  constructor(private readonly farmService: FarmService) {}

  @Post()
  create(@Body() createFarmDto: CreateFarmDto) {
    return this.farmService.create(createFarmDto);
  }

  @Get()
  findAll(): Promise {
    return this.farmService.findAll();
  }

  @Get(':id')
  findOne(@Param('id') id: string) {
    return this.farmService.findOne(+id);
  }

  @Patch(':id')
  update(@Param('id') id: string, @Body() updateFarmDto: UpdateFarmDto) {
    return this.farmService.update(+id, updateFarmDto);
  }

  @Delete(':id')
  remove(@Param('id') id: string) {
    return this.farmService.remove(+id);
  }
}

What is the motivation / use case for changing the behavior?

I'm sorry. this is my code (deleted)

[hongdor]

I solved it

I added <"webpack" : true > in the nest-cli.json file

(you can check the contents in the document below https://docs.nestjs.com/cli/monorepo#cli-properties)

{
  "collection": "@nestjs/schematics",
  "sourceRoot": "src",
  "compilerOptions": {    
    "webpack": true,
    "plugins": [
      {
        "name": "@nestjs/swagger",
        "options": {
          "classValidatorShim": false,
          "introspectComments": true
        }
      }
    ]
  }
}
