SW5.2.1 Upgradation Failed


I am in process of upgrading my Shopware to 5.2.1.

I have completed Data Migration. After CleanUp i got the below error…

Fatal error : Declaration of Shopware\Components\DependencyInjection\Container::reset() must be compatible with Symfony\Component\DependencyInjection\ResettableContainerInterface::reset() in  engine/Shopware/Components/DependencyInjection/Container.php  on line  35

Could anybody help me to solve this issue.

Thanks in Advance.

same here… does anybody have an idea how to fix this?!

I wouldn’t update yet, there are currently too many problems. See the forum. For example I have to refactor my theme. I hope you are testing the update.

Hi, thanks for your request. But at the end you fixed it?

Best regards

I have to do that, before updating.
