After successfully submitting a feed, when we call get_feed(FEED_ID), it always throws this error:

Can you please fix it?

we use this method successfully. do you have another class named Feed in your codebase and what is its namespace? the one it intends to use has a build_from_hash method https://github.com/ericcj/amz_sp_api/blob/main/lib/feeds-api-model/models/feed.rb#L222 but i wouldn't be surprised if there was a bug in this line that somehow is picking up yours https://github.com/ericcj/amz_sp_api/blob/main/lib/api_client.rb#L239

You most likely have a report model, add this method to your model.

Class Report 

…

def self.build_from_hash(data)
   AmzSpApi::ReportsApiModel::Report.build_from_hash(data)
  end

…

end

Thank you @mendywoly. You are correct. It works perfectly now.
