Broken $data reference

[cogor]

In first, thank for your great work!

I have two fields:
password – type String
repeatPassword – const with $data reference to "1/password"
When I set the same values in both input, I get an error than a field is incorrect, but that is not true.
In error I see incorrect allowedValue – undefined.
