Issue with the polymorphism association

[arabakevin]

When I use a where on a model with polymorphic association i have an error

Inbox::Row.where(
          item: context.sub_item,
          module: 0,
          organization: context.organization,
          project: context.project
        ).first

In my model

    belongs_to :item, polymorphic: true

i have this error
