Mike, Can you provide an example of your expression? It appears the expression is returning a Boolean value, when the desired and required format is a Date.

From the error, it seems you are trying to treat a Boolean variable as a 'Date' variable in an expression. I would look into the corresponding rule and make sure the value passed is of the correct data-type. Test the rule from the rules interface first. If that works as expected, check the data type you are passing into the rule (from the process). Hope this helps.
