Hey there. Running into an issue with the generated client. I have a schema where one of the properties is an array of string arrays. It is returned in an API response and it looks like the following:

      "Foo": {
        "type": "object",
        "properties": {
          "sortBy": {
            "type": "array",
            "items": {
              "type": "array",
              "items": {
                "type": "string"
              }
            }
          }
        }
      },

When I make an API call using the generated client, I get this error:

Error: encountered an unknown type during deserialization object

The stacktrace points to the generated models. When I inspect the generated model, I see that the a few things are off.

The code fails during deserialization in this function. Looks like the wrong function is invoked getCollectionOfPrimitiveValues

export function deserializeIntoFoo(foo: Partial<Foo> | undefined = {}) : Record<string, (node: ParseNode) => void> {
    return {
        "sortBy": n => { foo.sortBy = n.getCollectionOfPrimitiveValues<string>(); },
    }
}

The schema is typed incorrectly. It should be string[][]

export interface Foo extends Parsable {
    /**
     * The sortBy property
     */
    sortBy?: string[];
}

Also I changed the OpenAPI spec a few different ways and here are my findings.

1. Untyped the nested array. Same error. The property is typed as UntypedNode[]
2. Changed the nested array to object type. No error, but in the response the array value is parsed as an object { "0": "updatedAt", "1": "DESC" }
3. Removed properties from Foo. No error, but Foo is no longer typed correctly.
