RailsEventStore::AsyncHandler: undefined method `transform_keys'

Using rails_event_store@2.12.1 or 2.14.0

I have some ActiveJobs that include RailsEventStore::AsyncHandler.

Whenever I try to perform a job with them, they explode.

async_handler_helpers.rb:17:in `block (2 levels) in with': undefined method `transform_keys' for 

#<Videos::CreatedEvent:0x0000000115fb43c8 
  @event_id="d9c1b31a-f3a6-42ef-abd2-d1fe20363f91",
  @metadata=#<RubyEventStore::Metadata:0x0000000115fb42b0 
    @h={

    }>, 
  @data={:gym_id=>1, :video_id=>10}> 
(NoMethodError) irb(main):017> Gyms::UpdateMeteredUsageJob.perform_now(event)

Looks like it's happening here
