ES Module error

[wingy3181]

Hi,

I am just trying to run node script.js

with script.js contents as follows:

import CognitoSrpHelper from "cognito-srp-helper";

...

and i get the following output:

$ node aws-incognito-auth.js
node:internal/process/esm_loader:40
      internalBinding('errors').triggerUncaughtException(
                                ^

Error [ERR_UNSUPPORTED_DIR_IMPORT]: Directory import '/project/node_modules/.pnpm/[email protected]/node_modules/buffer/' is not supported resolving ES modules imported from /project/node_modules/.pnpm/[email protected]/node_modules/cognito-srp-helper/dist/esm/index.js
Did you mean to import [email protected]/node_modules/buffer/index.js?

Also within the package.json I have set the type: "module"

I noticed in the source code it has the following line

import { Buffer } from "buffer/"; // use the browser compatible buffer library

Obviously there is a reason you are using buffer/....... but how can i get this working then?

Hey @wingy3181 ,

Having trouble replicating the issue. Could you give me details about your environment? e.g. node version, pnpm version, full package.json, operating system maybe? Anything you can think of

Want to match your environment as closely as possible

Hi @simonmcallister0210

Here is repo where i have the issue in isolation
https://github.com/wingy3181/cognito-srp-helper-issue-52

It has the node version i am using in the .nvmrc file and the pnpm version in the package.json file

My OS is the latest macos 15.2

Thanks @wingy3181 , I cloned that repo and replicated the bug. Looks like an easy fix

I've published a beta version of the fix under 2.3.3-beta.1. Give it a go a let me know if it fixes the issue. If it does I'll merge the fix a publish

[simonmcallister0210]

Oh also.. while I was looking into the issue I noticed the package doesn't have a default export, so I've added that in too

[wingy3181]

All good @simonmcallister0210
LGTM!
Will let you close the issue when you publish the new version

[simonmcallister0210]

Nice, should be published now. Thanks for your help @wingy3181 🙂
