= ActiveJob::SerializationError < ArgumentError

(from /home/chedong/.local/share/rdoc)
------------------------------------------------------------------------
Raised when an unsupported argument type is set as a job argument. We
currently support String, Integer, Float, NilClass, TrueClass,
FalseClass, BigDecimal, Symbol, Date, Time, DateTime,
ActiveSupport::TimeWithZone, ActiveSupport::Duration, Hash,
ActiveSupport::HashWithIndifferentAccess, Array or
GlobalID::Identification instances, although this can be extended by
adding custom serializers. 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 GlobalID - such as
an unpersisted Active Record model.
