Миграция кода Mule 3 на Mule 4 и rest-router не поддерживается в Mule 4

У меня есть одно приложение - Mule 3, теперь мне нужно перенести его в Mule 4.

Я реализовал и изменил некоторый код, но из-за исключений этот тег не поддерживается, то есть 'rest-router' не поддерживается.

<rest-router:router templateUri="${igate.url}">

'rest-router' не поддерживается в Mule 4, нужна только замена этого тега или Как я могу перенести его в Mule 4.
