App bridge insllation issue - Shopify embedded app

Hi Guys,

I’m new on Shopify apps and working on an embedded app. I’m struggling to install app bridge to show a button in the title bar but its not working. I’m creating php/hmlt pages to show content in shopify app admin panel. Below is my code that I’m adding in the footer file at the end.

I have attached the screenshot of js errors from the console of Firefox. The chrome console has no error.

can somenoe please suggest and highlight me where I’m doing wrong, I’m following this tutorial https://www.udemy.com/course/shopify-app-development-in-php/

I’m very thankful for help on it.
