Exception: ActiveJob::SerializationError

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.
