Basic Inference not Working

I have been struggling to get basic type inferencing to work with trpc, react, and Drizzle ORM. This is what my server-side router is returning from the list method: 
export const organizationRouter = router({
  list: adminProcedure.query(async () => {
    const response = await listOrganizations.all();
    return response;
  }),
export const organizationRouter = router({
  list: adminProcedure.query(async () => {
    const response = await listOrganizations.all();
    return response;
  }),
Where, if I hover over the response in the return, it says the type is: 
const response: {
    id: number;
    name: string;
    description: string | null;
}[]
const response: {
    id: number;
    name: string;
    description: string | null;
}[]
However, on my client side, it says the type is any for the following: 
const organizationData = trpc.organization.list.useQuery();  
organizationData.data <---- ANY
const organizationData = trpc.organization.list.useQuery();  
organizationData.data <---- ANY
Why is this basic type inferencing not happening? I am using Drizzle ORM to infer the return type on the router response; could this have something to do with it? Does trpc not work well with ORM's that use inference?

It works if I do the following: 
list: adminProcedure.query(async () => {
    const response = await listOrganizations.all();
    return response as Organization[];
  }),
list: adminProcedure.query(async () => {
    const response = await listOrganizations.all();
    return response as Organization[];
  }),
But shouldn't trpc be able to inference it fine without having to force the output type? Seems like it defeats the point of trpc if I have to do that...
