Null type is ignored when generating object types

[lsdch]

Description

When generating types from schemas having "type": ["object", "null"], the null part is not accounted for: I expected that a union type <object type> | null would be generated, as is the case for scalar types

OpenAPI specification (optional)

{
  "components" : {
    "schemas": {
        "SomeObjectType": {
           "properties": {
             "someProp": { "type" : "string" },
             "someNullableProp": { "type" : ["string" , "null"]}, // Correctly generated as `string | null` ts type
           },
          "type": ["object", "null"] // ignored
        }
      }
  }
}

Configuration

openapi-ts -i openapi.json -o src/api

// openapi-ts.config.ts
export default defineConfig({
  input: "./openapi.json",
  output: "src/api",
  client: "fetch",
  format: "prettier",
  types: {
    dates: true,
    name: "PascalCase",
  }
})

System information (optional)

pnpm v9.1.2
node v20.11.0

Hey @lsdch, is this an OpenAPI 2.0 spec? Why isn't SomeObjectType in #/components/schemas?

[lsdch]

Sorry, I messed up the example, schemas was supposed to be here. Edited the issue to fix this. The actual spec I'm using is OpenAPI 3.1.0

Would you be able to create a reproducible example? I had a look at this yesterday and we have a type with array containing object and null in tests and it generates the expected result, so I wasn't able to reproduce

I just realized the issue was I am not using the latest version of openapi-ts, still on v0.42. Upgrading to v0.46 makes it all work as expected. Sorry, I'm closing this, apologies for wasting your time!
