Product Page View Error

I have the same error but it comes from cart, when i try to access to carts i get the error, or when i place cart block in the header i get that error in all pages.
Any idea what would be the issue ?

dev.tim → made their first commit to this issue’s fork.

according to Line 669 of modules/contrib/commerce/modules/order/src/Entity/Order.php there is probably missing a Store to that order. Maybe you have delete the store in the past, but order or cart was created when store was still exisiting?

Line 669 of modules/contrib/commerce/modules/order/src/Entity/Order.php:

    $timezone = $this->getStore()->getTimezone();

Just had a similar issue myself, I think it turned out that a store was deleted with a half completed order in the database that still referenced the deleted store, deleted all order entities and it seems to have solved the issue.
