`read` command ignored when script executed as part of `install.conf.yaml`, but works when executed manually in the terminal.

I have a script asking user to sign into App Store:

#!/usr/bin/env zsh

echo "App Store signin is required for MAS cli."

while true; do
  read "answer?Open App Store? [y/n]: "
  case ${answer} in
    [Yy]) echo "Sign in and close App Store to continue."; open -a "App Store" -W; break;;
    [Nn]) break;;
    *) echo "Incorrect answer.";;
  esac
done

When executed directly (by itself) in the terminal, it will prompt Open App Store? [y/n] and wait for user's input. But when executed as part of install.conf.yaml, like this:

- shell:
    - description: 'Checking App Store signin'
      command: scripts/appstore.zsh

It will display the first echo, then go into infinite loop ignoring everything inside, including the read line.

I have tried it the bash way as well i.e. read -r -p "Open App Store? [y/n] :" answer but it still goes into infinite loop and throws an error as -p in zsh works differently than in bash. I have tried the read command without the loop and it's completely ignored when the script is executed as part of install.conf.yaml, but again works as expected when I execute the script manually.

Any idea why?

You need to enable stdin (to get user input), stdout (to show the echos), and stderr (to show the prompt for read). Try this:

- shell:
    - description: 'Checking App Store signin'
      command: scripts/appstore.zsh
      stdin: true
      stdout: true
      stderr: true

Ah, ok. I had stdout and stderr enabled through defaults, but completely missed stdin. It worked like a charm, thank you.
