Your code looks fine. However, it seems like your version may not be updated? Datatables.php is for v6.0 below afaik? Please double check that you have the correct version?

Im facing same issue.

I've just upgraded to version 8, with:
composer require yajra/laravel-datatables-oracle:8.*
php artisan vendor:publish --tag=datatables --force

but Im still getting the error:

ErrorException in DataTables.php line 51:
Invalid argument supplied for foreach()

Please advise

@painter10 base on error log line 51, the new datatables.php config might not be overwritten. Maybe try deleting the config manually then publish again.

$builders = config('datatables.builders');
...
foreach ($builders as $class => $engine) {...

Also see https://yajrabox.com/docs/laravel-datatables/master/upgrade if you haven't checked it yet.

Thanks for suggestion. I think the problem was that I followed the Quick Start tutorial literally, so it was necessary to modify the setup, namely:
I had to delete config.php file in Bootstrap/cache, then in the config/app.php I changed
from:
Yajra\Datatables\DataTablesServiceProvider::class,
to:
Yajra\DataTables\DataTablesServiceProvider::class,
and now anyData() seems to work.
However, Im still struggling to display records in the datatable. Only headers are visible.

@AmirKaftari I could resolve the issue by clearing laravel cache. Thank you!
