(KeyError) key :array? not found in v5

After upgrading from 4.1.1 to 5.0.0, I'm getting this compile-time error:

** (KeyError) key :array? not found in: [
  retain_unlisted_types_on_load: [],
  nilify_unlisted_types_on_load: [],

    my_type_b: MyApp.MyTypeB

my_schema.ex:24 is:

Hello, interesting that you are using field instead of the macros polymorphic_embeds_one and polymorphic_embeds_many as documented.

Any reason?

Huh, I didn't notice. I don't know why it wasn't using polymorphic_embeds_one. I changed it and everything works fine. Thank you for the quick answer.
