What happended?

I tried setting up https://github.com/medusajs/b2b-starter-medusa on my local.

My 9000 port was being used by some PHP service & sounds like apple needs it. Doesnt allow me to kill it 🤷‍♂️

So I moved the backend to port 9001. Everything works fine other then when fetching product detail. Below is what I get in the product-json response.

"images": [
            {
                "id": "img_01K809S7XGN7PTGTRSQ530N6N9",
                "url": "http://localhost:9000/static/1760946855788-product_image.png",
                "metadata": null,
                "rank": 0,
                "product_id": "prod_01K806G7DKYVYNSA2TTQD8N7T8",
                "created_at": "2025-10-20T07:54:15.858Z",
                "updated_at": "2025-10-20T07:54:15.858Z",
                "deleted_at": null
            }
        ],

Expected behavior

The port in images.url should be 9001 but it seems to be hardcoded somewhere?

Actual behavior

The port in images.url wrongly is 9000.
