Hello, can you clarify which code snippet you used from the docs? And which page are you referring to?

[Ketlark]

Of course, it's this part : https://docs.medusajs.com/v2/resources/js-sdk#setup-js-sdk. I get rid of error but can't still used the SDK normally, even after tried multiple class import from it

[shahednasser]

Can you share your code block? Also, what type of project are you using it in?

[Ketlark]

import env from '#start/env'
import Medusa from '@medusajs/js-sdk'

export default class MedusaService {
  private static instance: Medusa.Admin
  private static MEDUSA_API_KEY = env.get('MEDUSA_API_KEY')

  static getInstance() {
    if (!MedusaService.instance) {
      MedusaService.instance = new Medusa.default({
        baseUrl: 'https://erp.mullo.fr',
        apiKey: this.MEDUSA_API_KEY,
      }).admin
    }
    return MedusaService.instance
  }
}

A sample nodeJS backend project that use Medusa backend API

Hello @Ketlark

I looked into the issue and it seems like our JS SDK is not compatible with the ESM implementation of Node.js and therefore it is not working at runtime and have type errors as well.

I will be working on it in the coming days and will let you know.

@thetutlage any news or blocking steps ? maybe i can help to fix it
