Dependencies not being injected on NestJS with Serverless stack and AWS

We are trying to integrate the NestJs with serverless stack and AWS . We have simple Controller that has a Service as a dependency.
when we make request to the controller the serviceObject that should contain the Service instance instead gives us undefined .

Below is our app.module.ts file contain

`

import { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
@Module({
controllers: [AppController],
providers: [AppService,
],
})
export class AppModule {}
`

Lambda.ts contain
`

import { NestFactory } from '@nestjs/core';
import { ExpressAdapter } from '@nestjs/platform-express';
import serverlessExpress from '@vendia/serverless-express';
import { Context, Handler } from 'aws-lambda';
import express from 'express';

import { AppModule } from './app.module';

let cachedServer: Handler;

async function bootstrap() {
if (!cachedServer) {
const expressApp = express();
const nestApp = await NestFactory.create(
AppModule,
new ExpressAdapter(expressApp),
);

nestApp.enableCors();

await nestApp.init();

cachedServer = serverlessExpress({ app: expressApp });
}

return cachedServer;
}

export const handler = async (event: any, context: Context, callback: any) => {
const server = await bootstrap();
return server(event, context, callback);
};

`

Main.ts

`

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';

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

await app.listen(3000);
}

bootstrap();
