Type inference is not ok. Is assuming the user properties are null

import { query } from "./_generated/server";
import { paginationOptsValidator } from "convex/server";
import { getAll } from "convex-helpers/server/relationships";

export const list = query({
  args: { paginationOpts: paginationOptsValidator },
  handler: async (ctx, { paginationOpts }) => {
    // Fetch a page of tutors
    const results = await ctx.db.query("tutors").paginate(paginationOpts);

    // Extract user IDs from the tutors
    const userIds = results.page.map((t) => t.user);

    // Fetch all user documents corresponding to the user IDs
    const users = await getAll(ctx.db, userIds); // Everything here is not null

    // Combine tutor and user information
    const page = await Promise.all(
      results.page.map(async (tutor) => {
        const user = users.find((u) => u._id === tutor.user); // THIS IS NOT NULLABLE...

        // Generate the URL for the user's profile image
        const imageUrl = await ctx.storage.getUrl(user!.image);

        return {
          ...tutor,
          user: {
            ...user,
            image: imageUrl,
          },
        };
      })
    );

    return {
      ...results,
      page,
    };
  },
});

    );

      ...results,
      page,
    };
  },
});

Hi @everyone with everything going on today I forgot to post on discord about our EU launch! We have a region in Dublin now! You can start using it immediately, even for folks on the free plan. https://news.convex.dev/we-finally-got-our-eu-visa/ Stay tuned for more regions but also stay tuned for more infra improvements where we improve latency for teams no matter where their servers are located. Just at the tip of the iceberg re all the optimizations we have lined up.
