Cannot debug nest js application in VSCode

I try to debug my nestjs application, I follow this article, https://javascript.plainenglish.io/debugging-nestjs-in-vscode-d474a088c63b but still cannot debug the application

This is my launch.json

   {
            "type": "node",
            "request": "launch",
            "name": "Debug Nest Framework",
            "args": [
                "${workspaceFolder}/api/src/main.ts"
            ],
            "runtimeArgs": [
                "--nolazy",
                "-r",
                "ts-node/register",
                "-r",
                "tsconfig-paths/register"
            ],
            "sourceMaps": true,
            "envFile": "${workspaceFolder}/.env",
            "cwd": "${workspaceRoot}/api",
            "console": "integratedTerminal",
            "protocol": "inspector"
        }

when I debugging the app seems start debugging but after get this error

return new TSError(diagnosticText, diagnosticCodes)
           ^
TSError: ⨯ Unable to compile TypeScript:
src/companies/companies.service.ts:13:49 - error TS2304: Cannot find name 'Company'.

enter image description here

How can I debug this app?

No need to config luanch.json..

  1. Open Vscode, and enter CTRL+SHIFT+P, select Toggle auto attach, choose always.
  2. Click the code line you want to debug
  3. npm run start

it will hit the line you want to debug

Instead of setting up an entire debug script, you can make use of the one Nest sets up in new applications for you. start:debug maps to nest start --debug which starts your server (after building it if needed) and adds the --insert-brk flag for node to know you need the debug port available. Then you can use VSCode to attach to port 9229 and start debugging.
