So I have a model with an embeds many relation running in production. I recently got an invalid relation when trying to call say model.photos and the following error was thrown.
NoMethodError: undefined method `[]' for nil:NilClass

I used model.unset('photos') to get rid of it so unfortunately I don't have any more to go on.
Have you seen it before? And if so do you know what the cause is?
