Thanks for the report @kshang

Currently the XTypes feature which includes the dynamic language binding is being refactored. It is well known that the current API is unstable for complex types (for instance array of structures).

[Mario-DL]

As the Dynamic Types refactor has been already introduced in the latest Fast DDS v3.0.0, we internally agreed to close all Dynamic-Types related issues.
We elaborated a Migration guide to help with the upgrade process to this new major release.

Please, feel free to reopen it if the issue persists.
