        # This little bit of code lets you add meta data to your existing exceptions, without having to
        # modify the exception, create a new exception (and updating rescues)!
        #
        # this was the best we could come up with to accomplish the following
        # - Add metadata to the exception by adding a `canvas_error_info` method
        # - Couldn't modify existing_exception_class directly
        # - New exceptions needs to be rescue-able by rescues for the existing_exception_class
        #
        # Now anytime you want to add metadata to an exception you do:
        # ```
        # raise Canvas::Errors::Reporter.raise_canvas_error(BasicLTI::BasicOutcomes::Unauthorized, "Duplicate nonce detected", oauth_error_info)
        # ```
        err = existing_exception_class.new(message)
        err.instance_variable_set(:@canvas_error_info, opts)
        class << err
          attr_reader :canvas_error_info
        end

# this makes the stack trace originate from the call before this one
        raise err, message, caller
