HOW-TO: How to use custom convertFromString in Node loaded as Plugin

[LUGGGI]

Hello,

I have a Node that uses a custom type. I've created the template specialization for convertFromString for that type.

When I use the Node directly, meaning registering it in the same file with factory.registerNodeType, everything works and the type gets converted.

But when I use the Node as a plugin I get the error that the specialization is not found:

You didn't implement the template specialization of convertFromString for this type: geometry_msgs::msg::Point_<std::allocator<void> >

I tried adding the template specialization to the file where I load the plugins, but that didn't work (I already thought it wouldn't work, but didn't have any other ideas.

Does anyone know how to do this? I would really appreciate it.
