[Humble] Buffer cannot transform b/c of TypeException

[RobinHeitz]

Bug report

Required Info:

• Operating System: Ubuntu 22.04.02
• Installation type: Binaries inside Docker Container
• Client library (if applicable): rclpy

Steps to reproduce issue

1. Launch static transform publisher ros2 run tf2_ros static_transform_publisher --x 1.0 --y 2.0 --frame-id world --child-frame-id child_frame

2. Launch the following node:

import rclpy
from geometry_msgs.msg import PoseStamped
from rclpy.node import Node
from tf2_ros import TransformException
from tf2_ros.buffer import Buffer


class TestPoseTransformation(Node):
    def __init__(self):
        super().__init__("test_pose_transform_node")
        self.tf_buffer = Buffer()

        self.pose_stamped = PoseStamped()
        self.pose_stamped.header.frame_id = "child_frame"
        self.pose_stamped.header.stamp = self.get_clock().now().to_msg()
        self.pose_stamped.pose.position.x = 0.1
        self.pose_stamped.pose.position.z = 0.4
        self.pose_stamped.pose.orientation.w = 1.0

        self.get_logger().info("Initialized Node")
        self.timer = self.create_timer(1.0, self.transform_pose_stamped)


    def transform_pose_stamped(self):
        try:
            t = self.tf_buffer.transform(self.pose_stamped, "world")
            print(t)

        except TransformException as e:
            self.get_logger().error(f"Could not transform: {e}")



def main(args=None):
    rclpy.init(args=args)
    node = TestPoseTransformation()
    rclpy.spin(node)
    node.destroy_node()
    rclpy.shutdown()

if __name__ == "__main__":
    main()

Expected behavior

I would expect that the pose_stamped is transformed from child_frame to world.

Actual behavior

TypeException: Type <class 'geometry_msgs.msg._pose_stamped.PoseStamped'> is not loaded or suported.
