With specific reference to this: https://shopify.dev/apps/online-store/theme-app-extensions/getting-started#step-1-log-in-to-your-partner-account
I have a Shopify App that now I want to embed some theme app extensions. So I try the CLI command shopify login which fires up a browser window, asking me to authenticate. I do, and the browser tells me Great! You’re in, and you can close this window now. So I do, as I am used to this pattern from other services.
However, the CLI responds with a cryptic message.
An unexpected error occurred on Shopify.> It doesn’t appear that you’re logged in. You must log into a partner organization or a store staff account.
So that is kinda interesting. Since this CLI App is needed to setup theme extensions, and I cannot login, what am I supposed to do? What is up with this system Shopify? I am using version 2.6.6 of the Shopify CLI codes.
