client unable to infer output types

I'm using v11 of trpc in tandem with drizzle on my backend. The client is a react native app. I've spent several hours trying to figure out why my outputs are inferred as Any. when I check the type on the backend I get the correct type so it's only happening on the client. for example product.list is a drizzle query that return an array of product but this is what I get.

type LIST /* LIST is Any */ = RouterOutputs["product"]["list"];

inferRouterOutputs<AppRouter>
type RouterOutputs = {
    product: GetInferenceHelpers<"output", {
        ctx: any;
        meta: object;
        errorShape: DefaultErrorShape;
        transformer: false;
    }, {
        list: QueryProcedure<{
            input: {
                cursor: number;
                pageSize: number;
            };
            output: any;
        }>;
    }>;
    user: GetInferenceHelpers<...>;
}

type LIST /* LIST is Any */ = RouterOutputs["product"]["list"];

inferRouterOutputs<AppRouter>
type RouterOutputs = {
    product: GetInferenceHelpers<"output", {
        ctx: any;
        meta: object;
        errorShape: DefaultErrorShape;
        transformer: false;
    }, {
        list: QueryProcedure<{
            input: {
                cursor: number;
                pageSize: number;
            };
            output: any;
        }>;
    }>;
    user: GetInferenceHelpers<...>;
}

if I create a simple proc that return an array or a string it is inferred correctly. for more detail about the stack I'm on vscode ts 5.4.5 trpc/client 11.0.0-rc.377 trpc/react-query 11.0.0-rc.377 drizzle-orm 0.30.10

I've found the issue I had import type { Context } from "@context"; in my import instead of ./Context not sure why ts didn't complain earlier. spent 5 hours total because of a single character.
