I’m new to Shopify App development. I’ve developed an app using a php template provided by shopify. It’s using Laravel & React. It’s 
Along with console error:
CodePudding user response：
About that console error you need to add this header on top of the page in views top_level.blade.php
<?php
$domain= $shop ?? Auth::user()->name ; ; // loged-in shopify store url example.myshopify.com
header("Content-Security-Policy: frame-ancestors https://".$domain." "."https://admin.shopify.com");
?>
This will resolve the does not match the recipient window's origin error.
After that try to open the app again or you can remove the entry from db and install the app again hope that will help.
