Application Error installing the app

What to do if you see an application error when installing the Fetchify Data Validation App for Shopify Plus Checkout Extensions

Updated over 4 months ago

If you're seeing an application error when trying to add an extension to your Shopify Plus checkout, then the most likely cause is that the store you're working on hasn't been upgraded to Checkout Extensions. The app is only compatible with stores that already have Checkout Extensions enabled.

Check your store settings and if the error persists even in a store which has upgraded to Checkout Extensions, please contact our support team.
