How to get theme app extension to communicate with app backend

Hi,
I’m trying to fire an API call from my theme app extension to my app backend.

I’ve set up an app proxy and I am setting my proxy URL to my APP URL from the Partners Platform, for example https://xxxxxxx-xxxxxxx-xxxxxxxx-xxxxxxxxx.trycloudflare.com/ is set to be routed if hit from “/apps/uni”. I am aware that it changes every time npm run dev is executed, and I am updating it accordingly.

After this, I’m trying to hit an API to the same endpoint, /apps/uni/v1/product.
I expect this to be handled in web/index.js which is run after running the npm run dev command.

Sample: app.get(“/v1/addresses”, async (req, res) => { console.log(“Request Received”); // const countData = await Product.count({ session }); res.status(200).send(“Success”); });

This gives me an HTTP 200 status response and goes through the app proxy, as checked on the network tab. However, there is no console.log statement output.
