RPAS date function mace caught Exception: IllegalParse: Parse

Hi,

I am trying to load a measure with a date through a rule with the use of date function in master domain like this:

mace -d . -run -expression "daytoexport = date("20150218","%Y%m%d")"

Now executing mace in domain

mace caught Exception: IllegalParse: Parse of - daytoexport = date(20150218,%Y%m%d) resulted in syntax error at -11.

mace exited with status: 4

The specs for the measure daytoexport
