Vacuum 0.16.3 always fails on "post-response-success" rule, dashboard panics

[AtomicTroop]

Running vacuum lint -dz openapi.yml always reports the post-response-success rule as an error.
As you can see from the reproduction spec included at the end of this message, a '200' response is present.

The warning includes the following message:
'postResponseSuccess' function has invalid options supplied. Example valid options are 'properties' = [200,201,300]: minimum property number not met (1)

If the '200' response is not present, linting will also report a warning on the operation-success-response rule correctly as expected. This rule seems to be a superset of post-response-success though, making the latter rule seem redundant.

Additionally, running vacuum dashboard -z openapi.yml and navigating to Operations > Check POST operations for success response panics:

panic: runtime error: index out of range [-1]
