@lubowu We check dynamically subscribing to a topic on this test.

Would you mind sharing a reproducible example, so we can analyze whether this is a bug or a misuse of the library?

Have you verified this problem?

[MiguelCompany]

@lubowu Sorry, we haven't had time yet to check this. We'll try to find some time for it this week.

Hi @lubowu,
Sorry for the delay in the response. I could reproduce the issue. Unfortunately, the current implementation supports simple types, but we are currently working on improving that. As a result, nesting the world struct inside the HelloWorldTopic would be invalid.

As a workaround, I suggest doing a couple of things, first, modifying the HelloWorld.idl (find it attached, HelloWorldMod), then applying the patch (also attached) that includes a correction when dealing with enums and finally edit the HelloWorldPublisher to publish messages of type HelloWorldTopicMod instead. Check if that overcomes the issue.

I am facing the same issue , and my backtrace on gdb is the exact same for FastDDS 2.13.2 Has there been a resolution for this yet ? @Mario-DL

[JesusPoderoso]

Hi @lubowu @bshantam97 , Fast DDS v3.0.0 has been released. It includes Dynamic Types refactor that may have fixed the described issue. Could you check if the problem 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.
