what: Fixed a wrongly classified platform error which is supposed to be handled by users. We were throwing the base exception class for this error whereas we should have been throwing a user error. Changed the implementation to use the errors.log_and_rethrow method.
why: Users executing templates were receiving an unhelpfull error message and a data job that terminated in Platform Error due to us throwing the most base Exception class from within the template.
testing: modified existing unit test.
