How to count joined table?

I'm trying to count rows returned by join for a query, basically the same as this: https://dba.stackexchange.com/questions/110850/count-rows-with-inner-joined-tables How to convert this to Drizzle? Any documentation I've missed regarding this kind of things?

SELECT t1.team_name,
       IFNULL(t2.num_players, 0) AS strength,
       t1.team_timestamp
FROM team t1
LEFT OUTER JOIN 
    (SELECT team_id, COUNT(team_id) AS num_players 
     FROM player 
     GROUP BY team_id
    ) t2
ON t1.team_id = t2.team_id
-- GROUP BY t1.team_id, t1.team_name, t1.season_id  -- **NOTE** - see discussion below
ORDER BY strength DESC, team_name ASC;

Argument of type 'SQL<unknown>' is not assignable to parameter

I have the following:

  const projects = await db
    .select()
    .from(project)
    .where(eq(project.ownerId, userId));

  const projects = await db
    .select()
    .from(project)
    .where(eq(project.ownerId, userId));

and the eq() gives an error like:

Argument of type 'SQL<unknown>' is not assignable to parameter of type 'SQL<unknown> | ((aliases: { id: MySqlColumn<{ data: string; driverParam: string | number; notNull: true; hasDefault: true; tableName: "Project"; }>; name: MySqlColumn<{ data: string; driverParam: string | number; hasDefault: false; notNull: true; tableName: "Project"; }>; description: MySqlColumn<...>; createdAt: My...'.

Type 'Name' is not assignable to type 'Chunk'.
            Property 'encoder' is missing in type 'Name' but required in type 'Param<unknown, unknown>'.ts(2345)
index.d.ts(80, 14): 'encoder' is declared here.

What could be the problem?
