is it possible to do conditional relational queries?

for example, i only want to retrieve the author object if their profile is public (a boolean on a user object)

export const users_relations = relations(users_table, ({ many }) => ({
  posts: many(posts_table),
}));

export const posts_relations = relations(posts_table, ({ one }) => ({
  author: one(users_table, {
    fields: [posts_table.owner_id],
    references: [users_table.id],
  }),
}));

export const users_relations = relations(users_table, ({ many }) => ({
  posts: many(posts_table),
}));

export const posts_relations = relations(posts_table, ({ one }) => ({
  author: one(users_table, {
    fields: [posts_table.owner_id],
    references: [users_table.id],
  }),
}));

if i do something like this

const post = await db.query.posts_table.findFirst({
      where: eq(posts_table.id, post_id),
      with: {
        author: {
          where: eq(users_table.public, true),
          columns: {
            username: true,
            display_name: true,
            public: true,
          },
        },
      },
    });

const post = await db.query.posts_table.findFirst({
      where: eq(posts_table.id, post_id),
      with: {
        author: {
          where: eq(users_table.public, true),
          columns: {
            username: true,
            display_name: true,
            public: true,
          },
        },
      },
    });

it works. but im getting typescript errors. is this a bug with drizzle? bump :/

same question here. the query works but typescript isnt happy

 
  const t = await db.query.campaigns.findMany({
    where: isNotNull(campaigns.userId),
    with: {
      user: {
        // @ts-ignore
        where: eq(users.clerkId, userId),
      },
    },
  });

 
  const t = await db.query.campaigns.findMany({
    where: isNotNull(campaigns.userId),
    with: {
      user: {
        // @ts-ignore
        where: eq(users.clerkId, userId),
      },
    },
  });
