class ActiveJob::SerializationError

Raised when an unsupported argument type is set as a job argument. We currently support NilClass, Integer, Fixnum, Float, String, TrueClass, FalseClass, Bignum, BigDecimal, and objects that can be represented as GlobalIDs (ex: Active Record). Raised if you set the key for a Hash something else than a string or a symbol. Also raised when trying to serialize an object which can't be identified with a Global ID - such as an unpersisted Active Record model.
