medusa: First install, storefront network error

I’d already tried that. Here’s my medusa-config.js.

// CORS to avoid issues when consuming Medusa from a client
const STORE_CORS = process.env.STORE_CORS || "http://localhost:3000";

Yesterday I updated medusa npm package to the dev version, used example storefront, and I still get the same error. Does anyone know a solution for this problem?

Hi @blackyzero,

It is difficult to say without seeing what request is causing the error, you can see this in networks tab in your browsers developer tools. A guess would be that the error is due to a CORS error. It appears as you are running the Next.js starter on 10.0.0.38:8000 but the CORS variable const STORE_CORS is set to localhost:8000 in medusa-config.js try changing that value and see if that solves the problem 😃

I want to share here my solution to the error below as I see it is mentioned here in some comments.

Access to XMLHttpRequest at ‘http://localhost:9000/store/products’ from origin ‘http://localhost:3000’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

STORE_CORS variable is initially set to process.env.STORE_CORS || "http://localhost:3000" which means it will take the value from env variable if that exists and is true, so instead what I did, I just changed STORE_CORS to “localhost:3000”(which is the client from where I make requests to the server).

By the way, in medusa-config.js it is pretty clear commented, but I somehow didn’t payed attention initially.

So, in your backend, in medusa-config.js file:

// CORS to avoid issues when consuming Medusa from a client
const STORE_CORS = process.env.STORE_CORS || "http://localhost:8000"; 

change STORE_CORS to your client localhost. In my case it was 3000.

// CORS to avoid issues when consuming Medusa from a client
const STORE_CORS = "http://localhost:3000"; 

Hope that helps!

I’m running an application in a Docker container based on the repository https://github.com/medusajs/docker-medusa. I’ve encountered an unhandled runtime error with the following call stack:
