I want to add product grid (assign product) in my custom module using UI Component.

I follow this ANSWER:

Magento 2 : How to add a product grid in custom module using ui component?

and I get the error like:

Fatal error: Call to undefined method Magento\Catalog\Model\ResourceModel\Product\CollectionFactory::getProductsReadonly() in /home/public_html/magento2110/app/code/[Namespace]/[Module]/Block/Adminhtml/Products/Edit/Tab/Product.php on line 133

If you already fixed above error so please help me to solve it or If you have another way to fix it so please let me know.

Issue is you are calling a wrong method with product object in

Step3: Create Product.php in Namespace\Module\Block\Adminhtml\Products\Edit\Tab\

Just comment following code block in above example,

/*if ($this->getItem()->getProductsReadonly()) {
            $productIds = $this->_getSelectedProducts();
            if (empty($productIds)) {
                $productIds = 0;
            }
            $this->getCollection()->addFieldToFilter('entity_id', ['in' => $productIds]);
        } */
