I have created a Shopify app named “My_Shopify_App” via the instructions here.
I deleted the application that was created in my partner’s account.
Deleted the local files on my PC.
Created a new application with:
npm init @shopify/app@latest
The name used was the same as the previously deleted application.
Using:
npm run dev
Shopify CLI complains with:
Couldn't find App with apiKey 43ca1debf6792ef67ba593b742ce5b30.
Creating a new application with a different name completes and starts normally.
