In file src/app/code/Custom/Catalog/view/frontend/templates/product/list.phtml at line 303 I have call to <?= /* @noEscape */ $block->getProductPrice($product); ?>

This call use src/vendor/magento/module-catalog/Block/Product/ListProduct.php

/**

     *

    {
        $priceRender = $this->getPriceRender();

        $price = '';
        if ($priceRender) {
            $price = $priceRender->render(
                FinalPrice::PRICE_CODE,
                $product,

@Nolwennig-Jeulin Hello,

I'm pretty sure that this error is due to the fact that you are using a Union type as a return type in your class :

[...]
public function getMinimalChildPriceAMount() : Base|bool  // <==== This is the error
// You might replace it with
public function getMinimalChildPriceAMount()  // <==== No return type
// Or with 
public function getMinimalChildPriceAMount() : ?Base  // <==== You need to return null instead of false
[...]

This error is caused by the interceptor generator not managing correctly Union Type return before the latest magento version.
You did not specify this but I'm assuming you are using Magento 2.4.5 or less as this issue was solved in magento 2.4.6.

You can take a look at this file if you want to apply patch to the core yourself but I'm pretty sure that removing the union typing is a better solution.
https://github.com/magento/magento2/blob/2.4-develop/lib/internal/Magento/Framework/GetReflectionMethodReturnTypeValueTrait.php

Anyway, this is not an issue on the current magento branch.
Kind Regards,
Baptiste

@engcom-Bravo I think the issue can be closed if @Nolwennig-Jeulin confirms the solution.
