here is main.ts file

 import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { CorsOptions } from '@nestjs/common/interfaces/external/cors-options.interface';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);

  const corsOptions: CorsOptions = {
    origin: '*',
    methods: '*',
    credentials: true,
    optionsSuccessStatus: 204,
  };

  app.enableCors(corsOptions);

  await app.listen(process.env.PORT || 3000);
}

bootstrap();

I have hosted other project with same set up without any problem here the whole project link

I attempted to transfer the business logic into another project, but encountered issues. I tried setting the output route as both "/dist" and "/" on the cyclic dashboard. All the environmental variables are configured on Cyclic, and I removed the "env" entry from the gitignore. I built an app, pushed the pre-made "dist" file, and hardcoded the port to 5025, but it still returns a "3000" port not responding error.
