Subcommand `purchase` is broken

[spargelz]

What happened?

Hey, when I try to use the command ipatool download 672904239 -b com.thehungrywasp.iamsober --purchase I get the error from the title. When I use it without the --purchase it tells me ERR error="license is required" success=false

Version

2.1.4

Relevant log output

ERR error="failed to purchase item with param 'STDQ': failed to purchase app" success=false
