oslo.messaging.simulator: TypeError: object of type 'int' has no len()

[Abhinav Srivastava]

I'm trying to use oslo.messaging.simulator tool to measure the performance of RabbitMQ/Oslo. I'm following the instructions as described in the OpenStack doc:

http://docs.openstack.org/developer/performance-docs/test_plans/mq/plan.html

However, when I run the following test I get "TypeError: object of type 'int' has no len()" error, both in the rpc-server and rpc-client side.

I'm using the following commands:

python simulator.py --url rabbit://<mycredentials>@myIP:port/ --debug true rpc-server

python simulator.py --url rabbit://<mycredentials>@myIP:port/ rpc-client -p 10 -m 100

The problem seems to be in the "call" test as my "cast" test seems to be working. I've pasted the detailed error message that I'm getting when I ran the "RPC call" test as described in the OpenStack doc.
