Illuminate\Database\QueryException
SQLSTATE[42000]: Syntax error or access violation: 1055 'es-vlad_ucsnemaservis.users.full_name' isn't in GROUP BY (SQL:

left join `subdivisions` on `users`.`subdivision` = `subdivisions`.`id` 
left join `positions` on `users`.`position` = `positions`.`id`

In config/database it says:

What version of mysql is hosted? Judging by this - 5.5.x.
Mysql learned to define functional dependencies between columns in version 5.7
On the other hand, I don’t understand the meaning of this query at all - there are still no aggregations there, why grouping?
It is likely that turning off only_full_group_byfromsql_mode
