I am facing strange issue on the Magento 2.4

I have upgraded my Magento store to the latest version, and after the upgrade, I am facing one strange issue while running upgrade command.

It's looks like Magento default issue.

SQLSTATE[42000]: Syntax error or access violation: 1061 Duplicate key name 'WISHLIST_CUSTOMER_ID', query was: ALTER TABLE `wishlist` ADD CONSTRAINT `WISHLIST_CUSTOMER_ID` UNIQUE KEY (`customer_id`)

enter image description here

Magento is going to add the foreign key in the wishlist table, but that key already exists, so as per the common logic, it should be skipped, but that is not happening and it's throwing error.

Apart from the above issue, I have found solution for it on stackexchange but that is not a correct way.

setup:upgrade SQL error after update from 2.2.8 to 2.3.1

You need to remove duplicate customer_id in wishlist table

List duplicate customer_id

GROUP BY customer_id
HAVING COUNT(customer_id) > 1;

Remove them

DELETE FROM wishlist WHERE wishlist_id in (...);
