@kuoiea you are reporting the issue against nameko version 2.12.0. Consider testing the issue against version or branch v3.0.0-rc

To me it seems, the stacktrace shows problems to connect to amqp broker. You are probably missing amqp broker configuration or the amqp server is currently not running.
