Checkout UI Extension Deployment Issue - Unauthorized Error and Password Protection

After I created the Checkout UI Extension and tried to deploy it, I encountered this page:


When I try to continue, I get an “Unauthorized” error.
Note: Before this, I was getting an error because the system couldn’t find the server in the class located at D:\e-sim\shopify.app.toml. I have resolved this issue and the service is now up and running on my PC.
The system sent many requests that failed due to “Unauthorized” errors

,I discovered that the app has a password protection feature for login. I attempted to remove this password, but the button to remove the password protection is unclickable


, Question: I cannot resolve this issue. I already have test payments set up and had a subscription previously. Is it mandatory to have an active subscription for each store to proceed?

The authentication issue is inside your app. not related to the online store password.

Please make sure you’ve set up the required environment variables in your application running on your PC. Thats likely whats causing this issue.
