I added some log in lib/pow/ecto.schema.ex

  defp missing_field?({name, type}, ecto_fields, _changeset_fields),
    do: missing_field?(name, type, ecto_fields)
  defp missing_field?(name, type, existing_fields) do
    not Enum.any?(existing_fields, fn
      {^name, ^type}  -> true
      {^name, e_type} -> not Type.primitive?(e_type)
      _any            -> false
    end)
  end

then I got these messages bleow...

**changeset_fields in Pow.Ecto.Schema is nil. I have no idea when this field is set.

so I got nil so it crashed at missing_field? function.**

I found this.

TODO: Require Ecto 3.8.0 in 1.1.0 and remove :changeset_fields

changeset_fields = Module.get_attribute(module, :ecto_changeset_fields) || Module.get_attribute(module, :changeset_fields)
