The subscription_url field type changed from str (required) to str | None (optional). This is a breaking change that could cause issues for consumers expecting this field to always be present.

Suggested change

	subscription_url: str | None = Field(None, alias="subscriptionUrl")
	subscription_url: str = Field(alias="subscriptionUrl")
