We are attempting to deploy an AWS Lambda using pulumi in typescript https://www.pulumi.com/registry/packages/aws/api-docs/lambda/function/ . We have an npm package we want to use in the lambda code, but are having a tough time getting pulumi to deploy the function with the package. Are there any examples available or pointers on how to get pulumi to do npm install and bundle the lambda code with packages?

we are attempting a base case of a lambda that has the package "uuid" installed.
Copy code
// src/index.ts
import * as aws from "@pulumi/aws";
import * as awsx from "@pulumi/awsx";
import { v4 as uuid } from "uuid";

const getLambda = new aws.lambda.CallbackFunction("getBucket", {
  callback: async (event, context, cb) => {
    const id = uuid();

    return {
      statusCode: 200,
      body: JSON.stringify({
        message: `Hello, API Gateway!. ${id}`,
        event,
        context,
      }),
    };
  },
});

const api = new awsx.classic.apigateway.API(`api-gateway`, {
  routes: [
    {
      path: "/bucket",
      method: "GET",
      eventHandler: getLambda,
    },
  ],
});

// Export the auto-generated API Gateway base URL
export const url = api.url;
Copy code
// Pulumi.yml
name: api
description: A minimal AWS TypeScript Pulumi program
main: src/index.ts
runtime: nodejs
and we get this error in the cloudwatch logs when invoking that lambda
