Explain this error on SCA "errorStatusCode": "400", "errorCode": "ERR_WS_ADD_ITEM", "errorMessage": "Failed when adding item to cart"

AI generated answer (using internal Slack threads):

The error you're encountering,

"errorStatusCode": "400", "errorCode": "ERR_WS_ADD_ITEM", "errorMessage": "Failed when adding item to cart"

, is typically thrown when there's an issue with adding an item to the cart in SuiteCommerce Advanced (SCA). This error can occur due to several reasons: 1. The item you're trying to add might not be available or active in the web store. Make sure the item is available for sale on the web store and is not marked as inactive. 2. There could be an issue with the item's configuration. If the item has mandatory fields that need to be filled out before it can be added to the cart, and these fields are not being filled out, this error can occur. 3. If you're using the CPQ module, ensure that the pricing is set up correctly. The error message

"Please enter a value for amount"

suggests that the pricing might not be set up correctly for the item. 4. There could be a problem with the session or the customer's cart. Old items that keep appearing in the cart or issues with editing the cart could indicate a problem with the session or the cart itself. To diagnose the issue, you might need to check the item's configuration, the web store settings, and the CPQ module's settings. You might also need to check the customer's session and cart. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
