Hi there

If you would like to have logging inside your Shopify Function in javascript you will need to use console.error(“your message”);

if (!targets.length) {
      // You can use STDERR for debug logs in your function
      console.error("No cart lines qualify for volume discount.");
      return EMPTY_DISCOUNT;
    }

To view the output you will view the extension runs inside your Shopify Partner Dashboard, they can be found Your App > Extensions > Your Function Name > See Details of a specific run of the function.

In the Logs (STDERR) section you should see your error logging.

You can review the documentation for more information on debugging.

Hi @lizk could you tell me how to make the See Details button appear? (lots of error don’t have this button) and how to log error with data variable like

console.error(“deliveryGroups”, deliveryGroups);

Thank you very much.
