post purchase extension proxy issue

[ecom-star-dev]

I am building a post purchase extension and I want to send a request to my server so I created a proxy, the proxy is working when I try to access it in the browser.

I get into an issue when I try to use the proxy URL inside the extension.

Proxy config -

import { createVerifyAppProxyMiddleware } from 'shopify-verify-app-proxy-middleware';

const { SHOPIFY_API_SECRET } = process.env;
const verifyAppProxyMiddleware = createVerifyAppProxyMiddleware(SHOPIFY_API_SECRET);

app.use('/api/proxy/', verifyAppProxyMiddleware, proxyRoutes);

proxyRoutes - 

import { Router } from 'express';
import { getAllFunnels } from '../controllers/funnel.controller';

const router = Router();

router.get('/funnels/get', getAllFunnels);

export default router;

 App settings -

Post purchase extension - 

// For local development, replace APP_URL with your local tunnel URL.
const APP_URL = 'https://something.trycloudflare.com';

extend('Checkout::PostPurchase::ShouldRender', async ({ inputData }) => {
	try {
		const response = await fetch(`${APP_URL}/apps/proxy-1`, {
			method: 'GET',
			headers: {
				'Authorization': `Bearer ${inputData.token}`,
				'Content-Type': 'application/json',
				'Access-Control-Allow-Origin': '*',
			},
		});

		if (!response.ok) {
			// Handle non-2xx responses
			throw new Error(`HTTP error! status: ${response.status}`);
		}

		const x = await response.json();
		console.log(x);

		// For local development, always show the post-purchase page
		return { render: true };
	} catch (error) {
		console.error('Failed to fetch funnels:', error);
		// Decide how to handle the error, e.g., not rendering the post-purchase page
		return { render: false };
	}
});

shopify.extension.toml file -

type = "checkout_post_purchase"
name = "some-name"

[capabilities]
network_access = true

 notice here is that I use [capabilities] and not [extensions.capabilities] like it says in the docs - link, when I try to use [extensions.capabilities] I got the following error when I tried to publish the extension -

 [                                                                                             │
│    {                                                                                           │
│      "code": "invalid_type",                                                                   │
│      "expected": "array",                                                                      │
│      "received": "object",                                                                     │
│      "path": [                                                                                 │
│        "extensions"                                                                            │
│      ],                                                                                        │
│      "message": "Expected array, received object"                                              │
│    }                                                                                           │
│  ]  

so I tried to use just [capabilities] and it didn't crash the publish but I have no idea how can I check if it's working besides actually succeeding to access a network. 

the response I get from the request in the extension -
