Theme not working correctly

What happened?

When I try to use Theme (https://www.pulumi.com/registry/packages/okta/api-docs/theme/) unless I put all the parameters, meaning nothing is optional, the stack creates successfully. When I try to change one parameter, Okta updates successfully but Pulumi reports an error.

Example

config:

    theme:
      # Required
      brand_id: bndcyf80bwlwrLLak5d7
      theme_id: thecyf80bx1G8OazH5d7
      # Optional
      bg_img: c:\\temp\\bg-image.png
      email_template: FULL_THEME # OKTA_DEFAULT, FULL_THEME
      end_user_dashboard: OKTA_DEFAULT # OKTA_DEFAULT, WHITE_LOGO_BACKGROUND, FULL_THEME, LOGO_ON_FULL_WHITE_BACKGROUND
      error_page: OKTA_DEFAULT # OKTA_DEFAULT, BACKGROUND_SECONDARY_COLOR, BACKGROUND_IMAGE
      favicon: c:\\temp\\favicon.ico
      logo: c:\\temp\\logo2.png
      pc_contrast: ffffff # 1662dd
      pc_hex: 1662dd
      sc_contrast: 000000 # ebebed
      sc_hex: ebebed
      signin_page: OKTA_DEFAULT # OKTA_DEFAULT, BACKGROUND_SECONDARY_COLOR, BACKGROUND_IMAGE

code:

def org_theme(theme):
    """
    Configures the Organization Theme in Customizations -> Branding
    """
    theme_config = Theme(
        resource_name="org_theme",
        background_image=theme.get("bg_img"),
        brand_id=theme.get("brand_id"),
        email_template_touch_point_variant=theme.get("email_template"),
        end_user_dashboard_touch_point_variant=theme.get("end_user_dashboard"),
        error_page_touch_point_variant=theme.get("error_page"),
        favicon=theme.get("favicon"),
        logo=theme.get("logo"),
        primary_color_contrast_hex=theme.get("pc_contrast"),
        primary_color_hex=theme.get("pc_hex"),
        secondary_color_contrast_hex=theme.get("sc_contrast"),
        secondary_color_hex=theme.get("sc_hex"),
        sign_in_page_touch_point_variant=theme.get("signin_page"),
        theme_id=theme.get("theme_id"),
    )
    return theme_config

Additional context

This is an Okta developer instance. The config and function work successfully the first time, but if you try to change a parameter or you create with a single parameter such as logo with the brand id and theme id then the update errors.

After the initial stack creation and with no additional updates to code or config, there is a change to the background image, favicon, and logo when you do pulumi up. This results in a failure.

The stack shows deleted but all of the customizations in Okta are not set to the defaults. I.E. the logo, favicon, background image, etc are still there.
