Expected behavior

shopify theme pull being run in a non-theme directory and in an CI/CD environment (→ docs) should display confirmation dialogue It doesn’t seem like you’re running this command in a theme directory. Are you sure you want to proceed? and not hang if SHOPIFY_CLI_TTY is set to 0.

Actual behavior

theme pull hangs, never completes, and displays no further message.
