Expected behavior

CLI not working for Post-purchase UI

I tried creating a new Shopify app. After that, I added Post-purchase UI extension. In the console I see:

To view this extension:
 1. Install Shopify’s post-purchase Chrome extension...
 2. Open the Chrome extension and paste this URL into it...
 3. Run a test purchase on your store to view your extension...

I create a test product, and create a test checkout: https://help.shopify.com/en/manual/checkout-settings/test-orders

Again. It’s a simple app, with a simple extension, without any changes, only a fresh project, created from CLI.

App working and I can see it in the admin dashboard. But this extension is not.

Issue number one: I don’t see anything after checkout, and before thank you page.

Issue number two: I tried to deploy this extension. And I see this:
