cachedJSON function Compile Error

[Ruckt]

This function below in the response protocol gives the following compile error: 'Call can throw, but it is not marked with 'try' and the error is not handled'

   private lazy var cachedJSON: JSON = {
        return JSON(data: self.data ?? Data())
    }()
