Thank :)

I get the same Error in Production (Heroku) did you manage to find a solution to this?

@ronakabhattrz @tmyengstrom Do either of you have a code snippet or even better demo app to reproduce the issue?

Here is a workaround we're currently using:

config/initializers/public_activity.rb

require "public_activity"

module PublicActivityExtensions
  module PublicActivity
    module FieldAccess
      def parameters
        p = read_attribute(:parameters)
        p = ActiveSupport::JSON.decode(p) if p.is_a?(String)
        p
      end
    end
  end
end

PublicActivity::Activity.class_eval do
  include PublicActivityExtensions::PublicActivity::FieldAccess
end

Thanks @maxsz :)

@ronakabhattrz @maxsz I’d still like to replicate and resolve this. I, too, have 2 apps deployed on Heroku but neither of those exhibit this particular error. So if either of you can provide more details that would be much appreciated.

I think this only happens if the column is not json(b) so that this code

public_activity/lib/public_activity/orm/active_record/activity.rb

Line 50 in bbb8f31

serialize :parameters, Hash unless [:json, :jsonb, :hstore].include?(columns_hash['parameters'].type)

won't serialize it as a Hash. Then when rendering it always expects a Hash:

public_activity/lib/public_activity/renderable.rb

Line 154 in bbb8f31

@prepared_params ||= self.parameters.with_indifferent_access.merge(params)

i am having the same issue

[ur5us]

@AdManteza What’s the database’s type for the parameter column?

[ur5us]

@maxsz Thanks for your input. I’ll double check that though I’m fairly certain that

public_activity/lib/public_activity/orm/active_record/activity.rb

Line 50 in bbb8f31

serialize :parameters, Hash unless [:json, :jsonb, :hstore].include?(columns_hash['parameters'].type)

is the way it is because Rails should automatically serialize back and force if the database column type is of json, jsonb or hstore. I have a suspicion that the issue is caused by a null value instead.
