I'm trying to manually create an aws lambda function: index.ts:

const testLambda = new aws.lambda.Function("testLambda", {
  code: new pulumi.asset.AssetArchive({
    ".": new pulumi.asset.FileArchive("./handler"),
  }),
  role: iamForLambda.arn,
  handler: "handler.handler",
  runtime: "nodejs14.x",
  environment: {
    variables: {
      foo: "bar",
    },
  },
});

handler/handler.ts:

export const handler = () => {
  console.log("meow");
}

this fails with:

"errorType": "Runtime.ImportModuleError",
  "errorMessage": "Error: Cannot find module 'handler'\nRequire stack:\n- /var/runtime/UserFunction.js\n- /var/runtime/index.js",

I'm sure I'm just referencing the handler wrong, but I've tried a few different things and can't figure it out lol.

Has your typescript lambda function been compiled to js?

Nope - it's typescript, and looking at the lambda payload it's ts there too

Correct, your lambda function code needs to be compiled from ts to js, in order to execute in AWS.

lmao that fixed it, thanks!
