This is a probably a bug in our side. I'll file a report for it. Thank you for bringing it to our attention.
Looks like it only happens when there are more than one product in the cart, but I'm sure.
Yes, it happens when two or more items in cart does not have enough quantity in store. We are working on the bug fix and it should be available soon-ish
For me, this happens when there is enough quantity in the store. It happens when an editor tries to release order hold in the Commerce Manager.
The order contains two products where one has quantity 2 and the second has quantity 1. And the first product has inventory quantity 38 and the second product has inventory quantity 48.
Is there any workaround? Our customer needs this order to be released as soon as possible.
Do you have a complete steps to reproduce? Or it simply happens with all purchases?
We'll make sure this get resolved ASAP.
I am not sure how to reproduce it. It is happening for a single order now (at least customer reported only one).
After upgrade this exception has occured several times:
