Deserialising specification files fails everytime

[auguwu]

I'm trying to deserialize a OpenApi object to build a crate that will generate types from a OpenAPI spec file, I tried with different specs (even one generated from this crate):

• https://youtrack.jetbrains.com/api/openapi.json
• https://raw.githubusercontent.com/stripe/openapi/master/openapi/spec3.json
• https://raw.githubusercontent.com/charted-dev/charted/main/assets/openapi.json - this one was generated with utoipa.

and it fails with:

# data did not match any variant of untagged enum RefOr

or

# missing field `headers`

I made a reproduction repository that the maintainers can try and see what is going on?
