Migration procedure from v10 to v11(AjaxRefresh)

We are considering migration from v10 (java) to v11 (.net).

Currently, we are verifying the application migration from v10 (java) to v11 (.net), but after migration, the following error occurred when testing the application.

After the screen transition, the following error occurs when AjaxRefresh the WebBlock / screen item including JS.

Error message: Unable to add header on server after sending HTTP header

I heard that there is no such error when migrating from v10 to v11. Can you tell me the correct migration procedure?
