Cart is null in response to "GetCartQuery"

[MUlasevich]

Describe the bug
After adding item to cart, cart is always null in response to "GetCartQuery", both for guest and logged in user .

Also, every add to cart action results in new cart being created.

To Reproduce
Steps to reproduce the behavior:

1. Run "npm create @bigcommerce/catalyst@latest", current version is 0.17.0
2. Manually fill all required variables in .env.local
3. Start application
4. Add any item to cart as guest user
5. Verify success message
6. Move to /cart route
7. Verify cart is empty while "cartId" is present in cookies

Expected behavior
User is able to see cart items and proceed to checkout

Screenshots

Additional context
Was able to reproduce the same issue using several different BigCommerce stores

@MUlasevich - I was also running into that issue. Did you try using a customer impersonation token instead?

@jtoromats i'm also having the same issue, using customer impersonation token v3/storefront/api-token-customer-impersonation helps to get cart, but login api returns empty customerAccessToken in this case

{
  data: {
    login: {
      customerAccessToken: null,
      customer:
          {
            entityId: 9,
            ......
          }
    }
  }
}

so it's not a solution either.

With v3/storefront/api-token login API works and returns customerAccessToken but query getCart returns null

{
    "data": {
        "site": {
            "cart": null
        }
    }
}

Tried to create new V2/V3 API token with all possible permissions, but the result is the same, is there any solution for this?

Hey @mhuretski, Customer Access Tokens will only be returned when using a Storefront Token instead of a Customer Impersonation token: https://developer.bigcommerce.com/docs/start/authentication/graphql-storefront#customer-access-tokens

You should be able to run pnpm create @bigcommerce/catalyst init which should generate a Storefront Token for you.

Hey @chanceaclark yes, I've created catalyst sales channel with BIGCOMMERCE_STOREFRONT_TOKEN token generated by pnpm create @bigcommerce/catalyst init, but cart is not returned for my existing stores.

I've tested it on a new store, on a brand new bigcommerce store everything works fine.

Issue seems to be connected with existing stores created before new api was released or having some specific store settings preventing new api from working correctly. I've tested it on 2 existing stores and I'm getting cart null there.

Should I create a ticket to customer support on this or perhaps there is some migration guide I missed for existing stores?
