Headers["Accept"] is leaking.

If I have

final Supabase _supabase = Supabase.instance;

 static final _users = _supabase.client.from('users');

  static Future<UserModel?> getUser(String userId, [String columns = '*']) async {
    final PostgrestResponse res = await _users.select(columns)
        .eq('user_id', userId)
        .maybeSingle()
        .execute();
  }

  static Future<List<UserModel>> getMatchingUsers(UserModel callingUser,
      [String columns = "*"]) async {
    final PostgrestResponse res = await _users.select(columns)
        .execute();
}

And I first call getUser, then this line is hit

    headers['Accept'] = 'application/vnd.pgrst.object+json';

If I then call anything else, such as getMatchingUsers, an error occurs because more than 1 row is returned.

I'm dumb and I shouldn't have reused static final _users = _supabase.client.from('users');
