Database error in query with JOIN Laravel v5?

Question

MySQL

I make a selection from the database (here is only part of the code, during which an error occurs)

if(count($rgColl) > 0){
                $this->projects->join('object_collection', function($join) use($rgColl){
                    $join->on('object_collection.object_id', '=', 'objects.id');
                    if(count($rgColl) == 1){
                        $join->where('object_collection.collection_id', '=', $rgColl[0]);
                    } else {
                        $join->whereIn('object_collection.collection_id', $rgColl);
                    }
                });
                $this->select[] = 'object_collection.object_id';
                $this->select[] = 'object_collection.collection_id';
                $this->group[]  = 'object_collection.object_id';
            }

If there is 1 element in $rgColl, then everything is OK, the result is returned normally
if the $join->whereIn('object_collection.collection_id', $rgColl);
gives an error message

SQLSTATE[42000]: Syntax error or access violation: 1064 check the manual that corresponds to your MySQL server version for the right syntax to use near '? where `objects`.`category_id` = ? group by `object_parameters_size`.`object_id' at line 1

I take the query code generated by Lara, and just execute it in MySQL Workbench, everything is cool, the data is returned.
The complete query looks like this

SELECT 
    `objects`.`id`,
    `objects`.`ord`,
    `objects`.`title`,
    `objects`.`art`,
    `objects`.`code`,
    `object_parameters_size`.`object_id`,
    `object_parameters_size`.`parameter_id`,
    `object_parameters_size`.`valint`,
    `object_collection`.`object_id`,
    `object_collection`.`collection_id`
FROM 
  `objects`
  INNER JOIN `object_parameters` AS `object_parameters_size` ON `object_parameters_size`.`object_id` = `objects`.`id`
    AND `object_parameters_size`.`parameter_id` = 1
    AND `object_parameters_size`.`valint` > 0
    AND `object_parameters_size`.`valint` < 500
  INNER JOIN `object_collection` ON `object_collection`.`object_id` = `objects`.`id`
        AND `object_collection`.`collection_id` IN (38,15,39,40,41)
WHERE
    `objects`.`category_id` = 1
GROUP BY `object_parameters_size`.`object_id` , `object_collection`.`object_id`
ORDER BY `objects`.`ord` ASC

There is some kind of anomaly.

Answer 1

Figured out what the problem was. Essence in the following
In the Illuminate\Database\Query\JoinClause class there was no whereIn method, as for the main body of the request. I added it, but it's a little wrong.
Initially, the line
It looks like this
AND when checking the syntax in via PDO in the select method of the Illuminate\Database\Connection class
We are getting an error. In general, there is no anomaly here, but entirely my blunt

Answer 2

Print the query using the toSql() method and double-check if your code column is escaped with back quotes. This is a reserved keyword. Most likely this is the problem.
The error clearly indicates that the request uses a reserved keyword.
