Hey team, I’ve been trying the pulumi crosswalk api gateway + lambda example in Pulumi’s docs, which defines routes using an OpenAPI specification. Their first typescript example is super simple, but I get a series of errors. Example here: https://www.pulumi.com/docs/guides/crosswalk/aws/api-gateway/

import * as aws from "@pulumi/aws";
import * as apigateway from "@pulumi/aws-apigateway";

// Create a Lambda Function
const helloHandler = new aws.lambda.CallbackFunction("hello-handler", {
  callback: async (ev, ctx) => {
    return {
      statusCode: 200,
      body: "Hello, API Gateway!",
    };
  },
});

// Define an endpoint that invokes a lambda to handle requests
const api = new apigateway.RestAPI("api", {
  routes: [
    {
      path: "/",
      method: "GET",
      eventHandler: helloHandler,
    },
  ],
});

export const url = api.url;

The first error I usually get is around needing an ARN (I think because it wants to run on behalf of a user), so try adding

apiKeyRequired: false

to the route

Unable to put integration on 'GET' for resource at path '/': Invalid ARN specified in the request
