Error compiling native msg (rosidl_typesupport_opensplice_cpp)

I have two posts

msg1 [Test.msg]
string address
char [8] buffer_data
bool status

msg2 [TestArray.msg]
std_msgs / header header
bool background_send
Test [] address_count
bool ch0

I use DDS from OpenSplice, and when compiling I use colcon. When I try to compile any messages (msg), I get the following error:

Traceback (most recent call last):
  File "/ opt / ros / crystal / lib / rosidl_typesupport_opensplice_cpp / rosidl_typesupport_opensplice_cpp", line 60, in <module>

As far as I could figure it out, this error is related to updating OpenSplice, when compiling it does not raise the Generated flag. How can I fix this problem?

You will need to update your Crystal installation to the latest Debian packages synced today (see The ros-crystal-rosidl-typesupport-opensplice-* packages fix this assert which happens when using the latest version of OpenSplice.
