Getting a strange error when decorator isn't used

[alanjackman]

Using this syntax:
assert_that(ixn_service.get_user_preferences(VALID_CMIS_ID).json().get('offlineVoicemailNotification'), False,
f"User preference didn't match Expected")
Instead of this syntax:
assert_that(some_service.get_user_preferences(VALID_CMIS_ID).json().get('offlineVoicemailNotification'), is_(False),
f"User preference didn't match Expected")

gives me this error:
Unable to display children:Error resolving variables Traceback (most recent call last):

assert_that() has two forms - assert_that(actual, matcher, [reason]) and assert_that(assertion, [reason]). The call you're making isn't of the 1st form, because the 2nd argument isn't a matcher, so it's falling back to the 2nd form.

As of 2.0, which we hope to release soon, type hints would warn you that you weren't calling assert_that() properly. Other than that, I'm not sure there's much better we can do about this.

OK, thanks for the information! Alan
