I am working on a Magento 2 project, and it was working fine until today, but now when I try to open it, the page is not working.

The following error is coming in error log:

PHP Fatal error: Uncaught TypeError: Argument 1 passed to Magento\Catalog\Model\ResourceModel\Product\Collection::addIsSaleableAttributeToFilter() must be of the type array or null, integer given, called in /home/olfwmbaph2hf/public_html/vendor/magento/module-catalog/Model/ResourceModel/Product/Collection.php on line 1582 and defined in /home/olfwmbaph2hf/public_html/vendor/magento/module-catalog/Model/ResourceModel/Product/Collection.php:2475
