Line 333 throws error on "config --get alias.example"

[anystar]

I'm writing a condition to ensure an alias is available and if its not it'll create the alias but running this code

$repo->run("config --get alias.example");

throws an empty error for line 333. Checking it myself $status = 1.

A similar command "status --short" which gives an empty response does not trigger this warning. Not sure whats going on here. Can you please look into this for me.
