I was investigating this,

The call which is throwing this exception is this->dataPtr->controller_manager_->update(sim_time_ros, sim_period);.

I check the details of the method in the controller manager class, and this call is always returning 0. The clock is wrong for some reason.

      const rclcpp::Time current_time = get_clock()->now();

Any thoughts?
