Unfortunately you are mistaken, ordinal_compass is not a WeeWX unit, rather it is a formatting option. The reason you are seeing the error is that WeeWX does not have any unit conversion functions defined for degree_compass units. Impossible to say much more without knowing what code you are using/changes you have made. Suffice to say that anything that attempts to explicitly or implicitly force a unit conversion from degree_compass will fail with a similar error.
