`mas install` errors when choosing 9.0.x and not installing Manage

[mudspringhiker]

MAS CLI version

21.1.0

CLI function used

install

What happened?

This was seen in a customer environment (TS022173386, which will be closed so creating this issue here). When running mas install, and choosing MAS 9.0.x, opting not to install Manage, the following error occurs:

Install IoT? [y/n] n
Install Monitor? [y/n] n
Install Manage? [y/n] n
Install Assist? [y/n] n
Install Optimizer? [y/n] n
Install Visual Inspection? [y/n] n
