How to treat mongoose/mongodb ObjectIDs as their serialized string values on the frontend?

TRPC Versions:

    "@trpc/client": "11.0.0-rc.403",
    "@trpc/react-query": "11.0.0-rc.403",
    "@trpc/server": "11.0.0-rc.403",

    "@trpc/react-query": "11.0.0-rc.403",
    "@trpc/server": "11.0.0-rc.403",

If I have a query procedure as follows:

 get_all_users: authenticatedProcedure.query(async ({ ctx }) => {
    const users = await User.find({})
      .select<{
        user_name: string;
      }>("user_name")
      .lean();

    return users;
  }),

 get_all_users: authenticatedProcedure.query(async ({ ctx }) => {
    const users = await User.find({})
      .select<{
        user_name: string;
      }>("user_name")
      .lean();

    return users;
  }),

and a simple frontend render on react as follows:

import { trpc } from "@/features/trpc";

const ViewUsers = () => {
  const { data, isLoading, error } = trpc.admin.get_all_users.useQuery();

  if (isLoading) return <div>Loading...</div>;
  if (error) return <div>Error: {error.message}</div>;

  return (
    <div>
      {data?.map((user) => <div key={user._id}>{user.user_name}</div>)}
    </div>
  );
};
export default ViewUsers;

import { trpc } from "@/features/trpc";

const ViewUsers = () => {
  const { data, isLoading, error } = trpc.admin.get_all_users.useQuery();

  if (isLoading) return <div>Loading...</div>;
  if (error) return <div>Error: {error.message}</div>;

  return (
    <div>
      {data?.map((user) => <div key={user._id}>{user.user_name}</div>)}
    </div>
  );
};
export default ViewUsers;

The frontend gives an error like:

Type 'ObjectId' is not assignable to type 'Key | null | undefined'.ts(2322)
index.d.ts(261, 9): The expected type comes from property 'key' which is declared here on type 'DetailedHTMLProps<HTMLAttributes<HTMLDivElement>, HTMLDivElement>'
(property) React.Attributes.key?: React.Key | null | undefined

Type 'ObjectId' is not assignable to type 'Key | null | undefined'.ts(2322)
index.d.ts(261, 9): The expected type comes from property 'key' which is declared here on type 'DetailedHTMLProps<HTMLAttributes<HTMLDivElement>, HTMLDivElement>'
(property) React.Attributes.key?: React.Key | null | undefined

However. The actual serialized value is of course a

string

string

for each

_id

_id

. What is the current expectation to handle these values? Of course, you can manually say

String(user._id)

String(user._id)

but is there a more appropriate method to handle this? Like a way to inform TS that these are strings and not ObjectId's on the frontend? I've tried my best to look at some other threads mentioning it, they however seem to mention declaring additional zod output schemas which feels quite cumbersome if you're intending on having varying different data returned.

The goal is to have the values treated as strings i feel.

Thanks for any help guys :)
