crash when sending custom array from websocket to ros2

[tal-grossman]

Issue Description:

I am able to send any msg type including custom srtuct with array (sequence accroding to yaml) from ros2 to websocket but integration service crashes when sending from websocket to ros2.

How To reproduce:

1. setup ros2 and websocket environment according to https://integration-service.docs.eprosima.com/en/latest/examples/different_protocols/pubsub/ros2-websocket.html
2. build custom msg and create mix file using colcon build --cmake-args -DMIX_ROS2_PACKAGES="client_interface_msgs"
3. create custom struct accorting to yaml_config guide and self exploration and try and error. see yaml configuration below.
4. run integration-service RoboxClientInterface.yaml
5. use node-red as websocket client and publish to (localhost) ros2 same custom msg.

Expected Result:

receiving custom struct as ros2 msg from websocket client.

Actual Result:

integration service crashers with this terminal msg:
[Integration Service][INFO] [is::sh::WebSocket::Server] Sent publication on topic 'robox_to_client': [[ {"msg":{"request":"test","theta":"","values":[{"key":"test_key","value":"test_value"},{"key":"test_kekey2","value":"test_value2"}],"x":"","y":""},"op":"publish","topic":"robox_to_client"} ]] [Integration Service][INFO] [is::sh::WebSocket::Server] Handle TCP message from connection '1': [[ {"op":"publish","topic":"robox_to_client","msg":{"request":"test","theta":"","values":[{"key":"test_key","value":"test_value"},{"key":"test_kekey2","value":"test_value2"}],"x":"","y":""}} ]] terminate called after throwing an instance of 'eprosima::is::json_xtypes::UnsupportedType' what(): Aborted (core dumped)

Yaml file (RoboxClientInterface.yaml): yaml_file

ros2 custom msg package (cient_interface_msgs): client_interface_msgs_package

Additional Information

• when sending same msg from ros2 termial to websocket client (node-red in my case), its working. example:
  ros2 topic pub /robox_to_client client_interface_msgs/msg/RoboxClientInterface '{request: "test", values: [{key: "test_key", value: "test_value"}, {key: "test_kekey2", value: "test_value2"}]}'
  and from node-red side got:
  {"msg":{"request":"test","theta":"","values":[{"key":"test_key","value":"test_value"},{"key":"test_kekey2","value":"test_value2"}],"x":"","y":""},"op":"publish","topic":"robox_to_client"}
