This is fine
schema:
type: string
examples:
NiceExample:
summary: Just a nice example.
value: fooBar
The second one can be compared to any other openapi spec and works just fine, but the one with the reference in the parameters breaks.
When I was searching for this bug, I traced it back to here.
Expected behavior
It should handle a reference in a parameter's example
