I have the following issue... turns out I cannot test locally my aws lambda function over serverless-offline plugin in serverless framework for nodejs. Cannot do a simple GET request.

I am able to deploy to aws lambda with serverless deploy command, but in order for better development experience of the team we need to deploy locally with serverless-offline, I followed this guide https://fauna.com/blog/develop-using-serverless-offline, but got stuck when I do a simple get request after running successfully serverless offline command. This I get when running serverless offline successfully serverless offline command output

But when I do a get request to the link http://localhost:3000/ through postman I get the following error

get request error

It basically says cannot find node:url module but I did npm install url, but still same error throwing. I will insert the project tree and files below:

serverless hello world tree structure

handler.js

//"use strict";

console.log("AJAJAJAJAJAJAJAJAJAAJAJ");

console.log("Printing module");
console.log(module.exports);

module.exports.hello = async (event) => {
  console.log("whaaaaat");
  return {
    statusCode: 200,
    body: JSON.stringify(
      {
        message: "Go Serverless v3.0! Your function executed successfully!",
        input: event,
      },
      null,
      2
    ),
  };
};

  • what do you get when you try to require the url from the nodejs cli. And could you please check whether the url module exists in the node_modules/ directory? – ysfiqbl Sep 23 '22 at 15:29

You need to install the actual serverless package itself as a dev dependency. Try this:

npm i -D serverless

Noted: remember to check the documentation of serverless-offline to know find the supported version of serverless package.

I fount in too node 14.17.3, framework 3.25.0 (local), plugin 6.2.2, SDK 4.3.2

I can workaround fixing by change require to import in UserFunction.js

set your node version to 16.17.0 or higher, and install serverless as a dev dependency

This happens because your version of Node 14.17.2 does not support node:url package anymore, as node:url was deprecated and removed.

Either downgrade your Node version to 12.x or downgrade your serverless-offline package to ^8.8.1
