App extensions Issue with connection when created in the UI

[geraintrees]

Hope someone can help.

I have an app that needs to be updated to support Theme App extension.  However I am having an issue in that I created a the Theme App Extension in the shopify App admin.

The problem now is when I try to update the theme app extension I get the following errors.

So the steps I am following

1. Run "shopify extension create"

2 selected the app and name the theme extension

3. From here I then have the following problem is I run "shopify extension register" I get the following error "

✗ You cannot register theme-app-extension because this app already has the maximum number of 1 registration allowed for this extension type."

Or if I run "shopify extension connect" I get the following error "✗ An unexpected error occurred on Shopify.

✗ You don't have any extensions of type theme_app_extension"

So my question is how do I update a theme app extension thats been created in the admin as currently I cant connect to it with the CLI and cant delete it in the admin?

Thanks G

I have not solved the problem by creating the .env manually and adding the ID etc.

Hi, thanks for the info. I have the same problem with an extension. How did you get the ID in your case?

[geraintrees]

I took the ID for the extension I created with in the admin UI from the URL and added it to the .env manually 

EXTENSION_ID=********

Hope that helps

Thank you so much! It worked.

Whenever you deploy the extension 

yarn deploy

this cmd automatically adds the EXTENSION_ID into your ENV file
