    }

Hi @SheheryarAamir,
as mentioned above, we are not sure that we found the best solution in #441.

Still, we wanted to include this in Springwolf 0.17.0, therefore the current solution is included and marked as beta.
More details soon on the website or in springwolf/springwolf.github.io#65

To avoid changing behaviour, we kept List as part of the defaults.

Thank you for opening the issue and starting on the PR.
We would love to hear from you if this resolves your issue and what is not optimal yet so that we can improve.

Thank you @timonback. Yes, solution implemented in version 0.17.0 partly resolve my issue as we are able to extract payload type in case it is wrapped in spring Message interface. But current version does not support custom interfaces e.g
MyInterface<String>

Great.
Have you tried the new configuration documented at https://www.springwolf.dev/docs/configuration/documenting-messages#unwrapping-the-payload ?
Instead of the java util Function, you will have to use your own fully qualified class name.

Thank you @timonback. Its working, able to extract payload type from custom interface.
