undefined method `fetch' for #<NewRelic::Rack::DeveloperMode>

[bogdanRada]

It seems this gem is incompatible with Newrelic gem Here is some backtrace:

Any ideas how to make it work?

I used this proxy class:

class RackPhpProxy < Rack::Proxy

  def rewrite_env(env)
    request = Rack::Request.new(env)
    if request.path =~ %r{\.php}
      env["HTTP_HOST"] = "localhost"
      env["REQUEST_PATH"] = "/php/#{request.fullpath}"
    end
    env
  end
end

i think is happening probably because the initialize method should receive first argument the application and then the options hash.

[bogdanRada]

if i redefine the initialize method from Rack::Proxy like this:

class RackPhpProxy < Rack::Proxy
  def initialize(app = nil, opts= {})
    @app = app
    super(opts)
  end

   def rewrite_env(env)
    request = Rack::Request.new(env)
    if request.path =~ %r{\.php}
      env["HTTP_HOST"] = "localhost"
      env["REQUEST_PATH"] = "/php/#{request.fullpath}"
    end
    env
  end
end

The issue dissapears , but instead the connection fails to localhost with timeout, but that probably is just my configuration wrong or something.

I think should be fixed in the gem itself.
