Apollo 3 pagination with Field Policies

Remove updateQuery callback function completely:

fetchMore({ variables: { offset: data.users.length } });

And change your cache to:

import { offsetLimitPagination } from "@apollo/client/utilities";

const cache = new InMemoryCache({
  typePolicies: {
    Query: {
      fields: {
        users: offsetLimitPagination(),
      },
    },
  },
});

So your query in qraphql must have offset and limit arguments.

Other options are: concatPagination and relayStylePagination

If you need to distinguish different request to same field users ex. put keyArg: offsetLimitPagination(["filters"]) and query your users with filters arg. Cache will store it separately.
