encountered the "Controller manager not available" error when using the spawner for diffdrive_controller,

Same problem, have you solved it?

[nisarganc]

I've been encountering the same problem with spawner for joint_state_broadcaster. The issue seems to be from gazebo ignition plugin for differential drive controller.

@civerachb-cpr do you think that your latest PR should fix this issue?
#233

[civerachb-cpr]

It might, though this issue predates Jazzy. The issue that #233 fixes appears to be specific to a new update to ros_controllers; when the Jazzy simulation was first released the timeout wasn't an issue, so something's changed between then and now on the controller front.

I suspect #233 won't hurt, but it may not completely solve the problem either.

Could it be related to #243?

It's not entirely clear which launch file @zahra370 is running here, but in the other issue it is due to the Gazebo simulation not being started.
