Issue with accountDeletionDate in CurrentUser.yaml

[Rexios80]

accountDeletionDate:
    oneOf:
      - $ref: ./Date.yaml
      - nullable: true

I think something is wrong with this piece but I don't know enough about the OpenAPI specification to fix it.

Here are some links I've found regarding this:
Redocly/redoc#1303
https://stackoverflow.com/questions/40920441/how-to-specify-a-property-can-be-null-or-a-reference-with-swagger

I tried doing some of the things in those links but I ended up just making it worse

Another note on this is I'm pretty sure OpenAPI 3.1 supports this, but I tried upgrading to it and everything broke.

As we are still on 3.0 we have to fix this with the:

type: string
nullable: true

method. Once we go to 3.1 we need to change this to:

oneOf:
  - type: 'null'   # Note the quotes around 'null'
  - type: string

or:

type:
  - 'null'   # Note the quotes around 'null'
  - string

Although 3.1 is currently so incredibly unsupported by everything it will likely be quite a while until that transition happens...

This did not generate code with the date as nullable

[Foorack]

Question is if the generator can even do that. This is the only variable in the spec right now that tends to be present with value null, rather than simply not being present in the first place, like all other variables.

@Rexios80 How does it do with variables which are not required? Does it mark those as nullable? Would marking accountDeletionDate as non-required fix the generation?
