Ambiguous column issue when using eloquent with for the join.

[mchourishi]

Hi,
I am using Datatable 9 on Laravel 6.

I have a model (FileAttachment) with softDelete enabled that has a join with users.
$files = FileAttachment::with('creator');

Now mostly everything is working except I am getting an error when I try to filter on users column (which is a relation)
My code for filter column is

->filterColumn('users.name', function($query) use($request,$likeOperator){
                        // column Uploaded By
                        if (isset($request->columns[5][self::SEARCH][self::VALUE])) {
                            $searchValue = $request->columns[5][self::SEARCH][self::VALUE];
                            $query->whereHas('creator', function ($instance) use($likeOperator, $searchValue){
                                $instance->where('users.name', $likeOperator, "%$searchValue%");
                            });
                        }
                    })

When I filter on column I get the following error

SQLSTATE[42702]: Ambiguous column: 7 ERROR:  ORDER BY "created_at" is ambiguous
LINE 1: ... "file_attachments"."deleted_at" is null order by "created_a...
                                                             ^ (SQL: select * from "file_attachments" left join "users" on "users"."id" = "file_attachments"."creator_id" where LOWER(CAST("users"."name" as TEXT)) LIKE %%cms%% and "file_attachments"."deleted_at" is null order by "created_at" desc limit 100 offset 0)

Is there a way to resolve this easily?
