Steps to reproduce

2. Click on the wishlist button in the product.
3. Now you can find the below error message.

Fatal error: Uncaught TypeError: Argument 1 passed to Magento\Catalog\Pricing\Price\ConfiguredOptions::getItemOptionsValue() must be of the type float, boolean given, called in /opt/lampp/htdocs/SVEP4087/vendor/magento/module-catalog/Pricing/Price/ConfiguredRegularPrice.php on line 74 and defined in /opt/lampp/htdocs/SVEP4087/vendor/magento/module-catalog/Pricing/Price/ConfiguredOptions.php:24 Stack trace: #0 /opt/lampp/htdocs/SVEP4087/vendor/magento/module-catalog/Pricing/Price/ConfiguredRegularPrice.php(74): Magento\Catalog\Pricing\Price\ConfiguredOptions->getItemOptionsValue(false, Object(Magento\Wishlist\Model\Item)) #1 /opt/lampp/htdocs/SVEP4087/vendor/magento/module-catalog/Pricing/Price/BasePrice.php(32): Magento\Catalog\Pricing\Price\ConfiguredRegularPrice->getValue() #2 /opt/lampp/htdocs/SVEP4087/vendor/magento/module-catalog/Pricing/Price/FinalPrice.php(44): Magento\Catalog\Pricing\Price\BasePrice->getValue() #3 /opt/lampp/htdocs/SVEP4087/vendor/magento/module-catalog/Pricing/Price/ConfiguredPrice.php(101): Mage in /opt/lampp/htdocs/SVEP4087/vendor/magento/module-catalog/Pricing/Price/ConfiguredOptions.php on line 24

Is there any suggestion of how to fix this in a site running < 2.2.7 ?

A plugin approach does not work due to the parent::getValue() method call elsewhere which means custom code won't kick in (as per https://github.com/magento/magento2/issues/11699).

[ishakhsuvarov]

@chris-pook If I understood your problem correctly, creating a composer patch with the https://github.com/magento/magento2/commit/0fc15747f05571cd6b164c01e1f1b6168e37a468 commit should do the trick without any customizations.

Hello @Sathishkumar8731 Same issue accrued in magento 2.2.4 and for zero price downloadable product and it's come from the ConfiguredRegularPrice.php file , and i just made change bellow in getValue()

public function getValue()
{
$basePrice = parent::getValue();
$basePrice = (float)$basePrice;
return $this->item
? $basePrice + $this->configuredOptions->getItemOptionsValue($basePrice, $this->item)
: $basePrice;
}
