Discriminator mapping throws validation error on valid discriminator mapping and accepts incorrect one.

Example found on https://swagger.io/docs/specification/data-models/inheritance-and-polymorphism/ in the section "Mapping Type Names"
The mapping section doesn't work with $ref references, but is a string that is being used as reference

If I add a mapping as found on the openapi spec site, i get a validation error that he expects a Reference object, but that is incorrect.
If i replace it with a Reference object, this libary says it's correct, but swagger ui and swagger editor say they expect a string and not an object.

Can this be fixed? For now I can just not fill in a mapping, but I prefer I could fill it in.

Never mind, I looked incorrectly. The issue was in my code.
