Why is my app proxy not redirecting in theme app extension?

I am trying to build a Theme app extension, and I am trying to access the Shopify app backend api from extension.


I tried setting up proxy in partner dashboard.

Proxy configuration:

subpath-prefix : apps

subpath : get-timers

Proxy url : https://a3c7-2401-4900-1cb0-cf6-6580-4caf-38c7-5819.in.ngrok.io/api/


And I am using the fetch, in the app.js file in Theme app extension to call the proxy:

The response I am getting is :

And If I change proxy url to any other (ex. https://cat-fact.herokuapp.com/facts/), I am getting a 404 status in the response.


I am spending too much time on this issue. If anyone could help me with this, greatly appreciated.

Uninstall and reinstall the app, the change in app proxy setup will be applied. It work for me.
