Shopify Debugging & Troubleshooting FAQs

Question 1

Why isn't my theme section showing up in the Customizer?

Accepted Answer

Ensure your liquid section file contains a valid {% schema %} block. A section must have a name defined in the schema to be visible in the theme editor.

Question 2

How do I output variable data for debugging in Liquid?

Accepted Answer

Use the | json filter, often wrapped in

 tags, like {{ product | json }}
, to view the raw object data directly on the storefront during development.

Question 3

What causes a 422 Unprocessable Entity error in Shopify?

Accepted Answer

This error typically occurs when the API request body contains validation errors, such as a missing required field (e.g., product title) or data that doesn't meet Shopify's formatting requirements.

Question 4

How do I debug Liquid errors in the Shopify theme editor?

Accepted Answer

Open browser DevTools (F12) while in the theme customizer and look for red error logs in the console which indicate specific line numbers and syntax errors.

Question 5

How can I verify if a Shopify webhook is authentic?

Accepted Answer

Compare the X-Shopify-Hmac-Sha256 header from the request with a SHA256 HMAC hash of the raw request body generated using your Shopify App's API secret key.
