in magento: 2.3, php: 7.2 I got same error: Deprecated Functionality: idn_to_ascii(): INTL_IDNA_VARIANT_2003 is deprecated ..

so I downgrade php version to 7.1 then its work. http://php.net/manual/en/migration72.deprecated.php

or another solution is to upgrade icu to ICU 4.6 http://www.linuxfromscratch.org/blfs/view/8.3/general/icu.html

to check icu current vesion uconv -V

INTL_IDNA_VARIANT_2003 (integer) Use IDNA 2003 algorithm in idn_to_utf8() and idn_to_ascii(). This is the default. This constant and using the default has been deprecated as of PHP 7.2.0.

INTL_IDNA_VARIANT_UTS46 (integer) Use UTS #46 algorithm in idn_to_utf8() and idn_to_ascii(). Available as of ICU 4.6.

Magento – Magento2.2 getCollection from Factory deprecated

I had the same exact issue and after digging through core code and reviewing generated classes, I found how.

If you look in vendor/magento/modulecatalog/Model/ResourceModel/Product.php

Notice:

\Magento\Catalog\Model\ResourceModel\Category\CollectionFactory $categoryCollectionFactory

In the constructor, we're expecting a CollectionFactory instance. If you look at the dynamically generated factory class you'll see:

<?php
namespace Magento\Catalog\Model\ResourceModel\Category;

/**
 * Factory class for @see \Magento\Catalog\Model\ResourceModel\Category\Collection
 */
class CollectionFactory
{
    /**
     * Object Manager instance
     *
     * @var \Magento\Framework\ObjectManagerInterface
     */
    protected $_objectManager = null;

    /**
     * Instance name to create
     *
     * @var string
     */
    protected $_instanceName = null;

    /**
     * Factory constructor
     *
     * @param \Magento\Framework\ObjectManagerInterface $objectManager
     * @param string $instanceName
     */
    public function __construct(\Magento\Framework\ObjectManagerInterface $objectManager, $instanceName = '\\Magento\\Catalog\\Model\\ResourceModel\\Category\\Collection')
    {
        $this->_objectManager = $objectManager;
        $this->_instanceName = $instanceName;
    }

    /**
     * Create class instance with specified parameters
     *
     * @param array $data
     * @return \Magento\Catalog\Model\ResourceModel\Category\Collection
     */
    public function create(array $data = array())
    {
        return $this->_objectManager->create($this->_instanceName, $data);
    }
}

Where the instance name is the collection.

In your case, change:

CostsFactory $costsFactory

To:

CostsCollectionFactory $costsFactory

use Example\Namespace\Model\ResourceModel\Cost\CollectionFactory as CostsCollectionFactory;

Then you can use the collection like so:

$costsCollection = $this->costsFactory->create();

$costsCollection->addFieldToSelect(...)
$costsCollection->addFieldToFilter(...)
...

Magento – Registry deprecated in magento 2.3, How to set data without Registry

I suggest you to read this article with discussion in the comments(!) -

https://www.atwix.com/magento-2/alternatives-for-deprecated-registry-class-magento-2-3/

Shortly: don't use session, use own class for registry.
