oneOf throws ValueError: Invalid value for ... on response parsing if not matching the last referenc

Hi there!
I'm using openapi 3.0.3 and I have an issue with my client: I expect an answer of the type Foo like

Foo:
  oneOf:
    - $ref: "#/components/schemas/Bar1"
    - $ref: "#/components/schemas/Bar2"
  discriminator:
    propertyName: type
    mapping:
      bar1: "#/components/schemas/Bar1"
      bar2: "#/components/schemas/Bar2"

And if my client receives Bar1, it will fail because in foo.py, there is a check for

allowed_values = ["bar2"]

Which throws:

ValueError: Invalid value for `type` (bar1), must be one of ['bar2']

I tested it a bit and it looks like it's taking the last ref in oneOf (Bar2).

Do you know how to fix it?
