Exception level filter not working for custom exception

[waltjones]

I tested here, and it's working for me. Is it possible the error class is nested?

Something like this

class TestController < ApplicationController
  class TestError < StandardError; end
end

will need to use

config.exception_level_filters.merge!('TestController::TestError' => 'ignore')

Otherwise, the filter depends on exception.class.name. You could try printing this for your exception class to be sure it matches the string you're using.
