APP Proxy not working on Development store

Hi, I’m new on shopify and working on an app, I am testing some shopify features and APIs to include these in my app. I’m testing APp proxy feature but it is not working on development store. I want to confirm that I’m setting it correctly.

This is how I set it.

Shopify Partner:
Sub path prefix: apps
Subpath: proxy
Proxy URL: https://abc.com/shopify_app_testing/my_proxy.php

Development Store:
I have embedded iframe using js in cart template file like

var target_html = '<iframe id="custome-app-iframe" src="//' + base_urlc + '/apps/proxy?shop=' + Shopify.shop + '" frameborder="0" scrolling="no" style="display:block;" width="100%" />';

$('#custome-app-iframe').html(target_html);

When I visit cart page, the following text displays

“Blocked by Content Security Policy”

instead of my proxy URL’s contents.

Am I setting APP Proxy correctly?

Thanks

Hey, There!

I’ve gone ahead and moved this post to our Developer board within our community. Hopefully in here someone can help you out with setting this up.

You may well have come across these already but these are the resources we have from our guides.

While not supported by our own team at Shopify, some of our community members may be able to lend a helping hand.

I did not get any reponse, is anyone there to mention some suggestions.
