NextJS & Keystone CMS, issues when connecting both in a monorepo

Hello everyone,

so I have a monorepo with NextJS and keystone cms, both are running trpc v10beta.15.

Screenshot 1: I receive a type error when trying to use the CmsAppRouter type in my NextJS when calling createTRPCProxyClient.
Screenshot 2: The tRPC files in the cms.

Does someone has a clue? Would be really thankful for any help
