Having issues with nested resources

Trying to call an edit (via a button in the todo_list show view) of the todo_item. Currently getting the error below.

I’ve been cribbing from the getting started rails guide, but creating more tailored views that show here is the todo_list and then here are all the associated todo_items on that list in a single view.

Maybe the TodoItem was deleted or maybe it belongs to another TodoList?
