OpenAPI reference not rendering on HUB

since yesterday the HUB documentation of my project can’t render anymore the references to openAPI files in my modeling project.
Unfortunately I don’t see any error in any of the openAPI files, everything seems to be validated. How can I check what’s wrong?

Found the reason.
In one of the openAPI.yaml files, I put by mistake a reference using double ## instead of one #.
In this case, stoplight does not detect a potential issue and consider it as valid (maybe it depends on my config).
—> however, then at HUB rendering time it had troubles. I fixed the reference in the .yaml file and now all is fine.

Good to hear @gianpaolo.campiglia. I would need to see where exactly you had that ## to get more context for why it was breaking.
