Então, o frontend (que roda no navegador) tentaria acessar `/openapi.json` e não conseguiria obter o OpenAPI schema.

Como temos um proxy com um prefixo de path de `/api/v1` para nossa aplicação, o frontend precisa buscar o OpenAPI schema em `/api/v1/openapi.json`.

    }

    await fs.promises.writeFile(
      filePath,
      JSON.stringify(openapiContent, null, 2),
    )
    console.log('File successfully modified')
  } catch (err) {
    console.error('Error:', err)
  }
}

const filePath = './openapi.json'

Поэтому фронтенд (который работает в браузере) попытается обратиться к `/openapi.json` и не сможет получить схему OpenAPI.

Так как для нашего приложения используется прокси с префиксом пути `/api/v1`, фронтенду нужно забирать схему OpenAPI по `/api/v1/openapi.json`.
