Internal server error when create cart using storefront API

Hi, I am getting the following error when calling the storefront api to create a cart and add an item:

“{“errors”:[{“message”:“Internal error. Looks like something went wrong on our end.\nRequest ID: … (include this in support requests).”,“extensions”:{“code”:“INTERNAL_SERVER_ERROR”,“requestId”:”…"}} ]}

I am using the official shopify library for PHP, this is the query sent (I modified the one that appears in this example: https://shopify.dev/docs/custom-storefronts/building-with-the-storefront-api/cart/ manage#step-1-create-a-cart-and-add-a-line-item)

$products = $storefrontClient->query(
            data: <<

I am also experiencing Internal Server Errors when trying to use the cartCreate mutation.

@fsepulveda Did you find a solution to this? Or is it simply a matter of waiting for Shopify?
