Self-generated API file with hard-coded "types"

[kmirojo]

Hi everyone,
I'm generating an API typescript file from an Open API .yml file, but something is happening.
My .yml file looks like this:

components:
  schemas:
    ItemPropertiesBase:
      type: object
      properties:
        type:
          type: string

    ItemProperties:
      allOf:
        - $ref: '#/components/schemas/ItemPropertiesBase'
        - type: object
          properties:
            prop1:
              type: boolean
            prop2:
              type: number
            prop3:
              type: number

but when I generate the code, the type prop from the ItemPropertiesBase is hard-coded, even though I only assigned a type, but not a value:

export type ItemPropertiesBase = {
    "type": string;
};

export type ItemProperties = {
    "type": "ItemProperties"; 
} & ItemPropertiesBase & {
    prop1: boolean;
    prop2: number;
    prop3: number;
};

The issue with this is that I need the type to be a string, but not a specific value, because otherwise typescript won't allow me to have a different type,
Is there a way to change this?

Hi @kmirojo

Seems as if you're running into compatibility issues with our "discriminating schemas" (see #422). Do you use a discriminator in one of your real-world types?

And can you please confirm, the expected outcome would be something along the lines of

export type ItemPropertiesBase = {
    "type": string;
};

export type ItemProperties = ItemPropertiesBase & {
    prop1: boolean;
    prop2: number;
    prop3: number;
};
