Hi @Mrzhou-coder,

Thanks for your contribution. I am afraid that the Dynamic Types API has several known issues. That is the reason why it is being refactored right now in #3392.

Hi @TechVortexZ, We are working on the new major version of Fast DDS (v3.0.0) where we have refactored the DynamicTypes. The problem should be solved, you can try to upgrade Fast DDS to Master and try it. Please note that this is a major release, so many APIs have been changed and until the official release Master is still unstable. Let us know if the problem has been resolved.

Hi @TechVortexZ, Fast DDS v3.0.0 has been released! Could you check if the issue persists?

[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.
