init dialog for adding a compute node is confusing

$ sudo snap install microstack --devmode --beta

$ snap info microstack | grep -e installed -e tracking

tracking: latest/beta
installed: ussuri (215) 386MB devmode

$ sudo microstack init

At first I tried entering a null value for the connection string as I wasn't aware of the workflow. The resulting messaging doesn't make sense.

Thanks for reporting this Peter. Would you suggest updating the line to be more detailed, such as:

"Please enter a connection string returned by running the add-compute command on the control node"

[Peter Matulis (petermatulis)]

That would improve the prompting message, yes.

But the resulting message (caused by pressing Enter, but maybe some other input as well?) also needs to be looked at. The second part ("is not valid. Please answer Yes or No.") is particularly perplexing.

[Corey Bryant (corey.bryant)]

Agreed, thanks Peter.
