Nullable and patern

[ntnchrrn07]

Hi,
I could not use for a string pattern and nullable, is it normal ?

OpenApiSpex.schema(%{
  title: "mySchema",
  type: :object,
  properties: %{
    dummy: %Schema{
      type: :string,
      nullable: true,
      pattern: "^[0-9]{3}$"
    }

}

I would like to allow :

{dummy: null}
and {dummy: "010"}

I have same problem here, nullable: true does not work with pattern, an workaround is "accept null" in your regex.

adding |^$ to end of your regex should works.

some like pattern: "^[0-9]{3}$|^$"
