Hi!
In general, if you set -u oh-my-zsh will start crying around (omz cli, for example, is not adapted for that).
While fixing it is easy in this instance, I'd rather recommend just avoiding using set -u or setopt no_unset. It'll then be more sustainable and will avoid other issues.
I'll close this, feel free to comment why you particularly need set -u.
Thanks for the report!
