404 error in crawling wps-rest OpenAPI YAML schemas

[Just van den Broecke]

Was quite a route, still not sure if the error stems from here:

• 404 Error was first noted in a GeoHealthCheck PR: geopython/GeoHealthCheck#315 .Travis test
• reported by GeoHealthCheck OpenAPI Validator (https://pypi.org/project/openapi-spec-validator/) that tests pygeoapi instance
• best is to follow the story at: geopython/pygeoapi#356, as I first thought the problem was within pygeoapi.

Especially this screenshot appears to hint to the schemas under https://github.com/opengeospatial/wps-rest-binding/tree/master/core/openapi/schemas
which were changed on the same day (jan 28, 2020) as the errors start occurring.

I am not well-versed in this schema lang, but could it be that this file:
https://raw.githubusercontent.com/opengeospatial/wps-rest-binding/master/core/openapi/schemas/input.yaml
has a $ref: input or is that valid syntax? (I am now almost sure as the 404 in screenshot comes right after that).
