Then no errors occurs

Actual

No error occurs

Runtime

When the rule is invoked
then following error occurs

 [Warning] Rule 'Invalid' failed: (1,2): error CS1733: Expected expression

Expected

The CLI should not allow to upload invalid rules (according to the rule language), an error should be produced

I like the suggestion but I think that the recently added invoke.rule command allows one to check for such error before uploading.
