Answer 1

The error is caused due to the product price is zero.

Since in default Magento while adding the wishlist the product price type is return as "float".

Refer the coding line: 24 in below file path

vendor/magento/module-catalog/Pricing/Price/ConfiguredOptions.php

Can you change the product price and then check it.

Answer 2

Remove generation/code

Run command:

bin/magento cache:flush

bin/magento setup:di:compile

Hope it will work.

Answer 3

It is the bug https://github.com/magento/magento2/issues/16479 You can choose one of options:

1. Remove zero price product from wishlist
2. Update Magento to v2.3.0 or upper
