[Bug]: Add to Cart Workflow broken since last update

[fxmb]

Package.json file

The commit 8 hours ago broke the add to cart workflow I believe:

   const cart = transform({ cartQuery }, ({ cartQuery }) => {
      return cartQuery.data[0]
    })

This query result from here: https://github.com/medusajs/medusa/blob/develop/packages/core/core-flows/src/cart/workflows/add-to-cart.ts#L47

returns the first cart that was created in the database.

I always get this error when trying to add to the cart using the addToCart Workflow:

Cart cart_01J801RD5JEWMPDS0V1AZZM0FP is already completed.

However, this cart (ending on FP) is not the one I am sending to the server, its an old cart from another customer...

This is the first cart ever created in our db, hence I assume some query is failing, sorted by date and returning the first [0] cart since its sorted by created_at.

@fxmb, thanks for the report. How are you consuming the workflow? Its input type changed in the latest release. You should pass the cart_id instead of cart now.

I'll add this to the release notes.

Ha that fixed it! Thanks for pointing this out so quickly

For everyone else:

 const workflowInput = {
    items: line_items,
    cart
  };

  await addToCartWorkflow(req.scope).run({
    input: workflowInput,
  });

becomes:

    items: line_items,
    cart_id: cart.id,
  };

  await addToCartWorkflow(req.scope).run({
    input: workflowInput,
  });

Hey,
At the moment, we are using Medusa v2.0.7 before upgrading to last version in the next weeks.
We had thus bug because of :

@medusajs/core-flows was not a dependency we had in our package.json, as we used this one: https://github.com/tinloof/medusa-dtc-starter-munchies/blob/main/storefront/package.json

Is it normal that we can have "@medusajs/framework": "2.0.7", and still have issues about 2.1.2 ? Did we missed something ?

We had the same error as @fxmb about already completed, and after wiping the database and starting fresh on data, now we have:

http:    GET /store/carts/cart_01JFD1KHDA6M00EC1YWZ8KYKW0?fields=%2Bitems%2C%20%2Bregion%2C%20%2Bitems
│ .product.%2A%2C%20%2Bitems.variant.image%2C%20%2Bitems.variant.%2A%2C%20%2Bitems.thumbnail%2C%20%2Bite
│ ms.metadata%2C%20%2Bpromotions.%2A%2C ← - (200) - 34.256 ms
│ error:   Value for LineItem.cart_id is required, 'undefined' found
│ entity: LineItem {

Our way to fix it force the version in our yarn.lock like this:

"@medusajs/core-flows@npm:2.0.7, @medusajs/core-flows@npm:^2.0.7":
  version: 2.0.7
  resolution: "@medusajs/core-flows@npm:2.0.7"
  dependencies:
    json-2-csv: "npm:^5.5.4"
  peerDependencies:
    "@medusajs/framework": ^2.0.0
    awilix: ^8.0.1
  checksum: 10c0/0e2e1a17a9f7442345afd179c4be8ce423f8b49bc4097e04b25a6178de2233669436b514e0056a80e6ecbc0131a60ba5a863aa3270b3a0e77a3b00a74d2d291a
  languageName: node
  linkType: hard

By putting this at the root of our yarn workspace :

"resolutions": {
  "@medusajs/medusa/@medusajs/core-flows": "2.0.7"
}

😿
Do you know a proper way to not have issues related to futur version in our actual codebase & version of ALL the @medusajs packages ?

The exact same issue is happening for me.
