I’m using ember-cli-rails to merge an Ember frontend and a ruby on rails backend, but I’m getting a build error. I’m also using puma-dev for a .test to spin up my servers. I’m fairly new to this, but I can’t seem to find what’s causing this error. Has anyone else encountered this before?

undefined method `has_key?’ for nil:NilClass Extracted source (around line #19):

      def action_encoding_template(action) # :nodoc:
        if @_parameter_encodings.has_key?(action.to_s)

I don’t see any function like this in the code base, so I assume it’s part of a node_module, or the compiling of ember. Here is the repo if more context would help: GitHub - wjacobs71086/keenmind: DnD notes app

I appreciate any and all insight as I’m trying to learn more about this tech stack!

It may be worth noting that if I change config > routes.rb to a new path, then when viewing the"/" path, I see the default rails page and no error. Then viewing the new path I get the error. This seems to indicate that the issue is the ember build and not the rails API.
