Understanding the “Errors During Checkout” and “Abandoned Checkouts” Alerts

If you see a warning like this in your Shopify Admin:

“There were errors during checkout starting May 13, 2025. Some customers have abandoned checkout or were able to submit orders.”

— it’s likely triggered by automated bot traffic, not real customers.

What’s actually happening?

These messages usually appear when bots hit your store and create fake carts, often adding hundreds of items at once or using absurd quantities like 830417, which no real customer would ever do.

Here’s an example of one such abandoned cart:

{
  "cart": {
    "buyerIdentity": null,
    "lines": [
      {
        "id": "gid://shopify/CartLine/b26b94db-aaac-4deb-bba2-93002a317c11",
        "quantity": 830417,
        "bundleId": null,
      },
      {
        "id": "gid://shopify/CartLine/198a0eda-9e90-405a-b82b-f61eb605cb57",
        "quantity": 830417,
        "bundleId": null,
      },
      {
        "id": "gid://shopify/CartLine/b440603e-c390-450e-890d-0bd417cfbf57",
        "quantity": 830417,
        "bundleId": null,
      },
      ...
    ]
  }
}

These bots don’t complete checkout, and Shopify blocks them from doing any real harm. Your store, bundles, and checkout process remain fully functional for actual customers.

Why Is Bundly Mentioned?

Bundly gets listed in the warning simply because it’s part of your checkout flow, but it’s not the source of the error. Our app does not block checkouts or prevent orders from being submitted. These warnings can appear whether or not a bundle is part of the cart.

Why Are Bots Even on My Site?

Totally normal. Bots visit almost every site on the internet. Shopify is designed to handle them securely. Read more about bots here: Understanding bots at Shopify.
