problem publishing with rosbridge suite

Question

Hello,

I have run this tutorial (I am using ROS Hydro) wiki.ros.org/rosbridge_suite/Tutorials/RunningRosbridge on running rosbridge example.

When I started the HTML page, I noticed that all work expect publishing the /cmd/vel topic. I am getting this error message

[ERROR] [WallTime: 1397113517.026746] [Client 4] [id: advertise:/cmd_vel:1] advertise: init() got an unexpected keyword argument 'queue_size'

[ERROR] [WallTime: 1397113517.035466] [Client 4] [id: publish:/cmd_vel:2] publish: Cannot infer topic type for topic /cmd_vel as it is not yet advertised

Do you have any idea how to fix this issue?

I tested the same code on another Hydro machine and it worked, but on my machine with the same configuration, I had the error above.

Thank you in advance

Can you share the rosbridge package version and HTML code you tested?

Answer 1

Refer to the github issue in rosbridge_suite. It was because incompatibility in rospy between groovy and hydro. Groovy version of rosbridge_suite has been re-released and should not have this error as of now.
